MAN CITY: No replacement for Kompany

Pep Guardiola started the summer looking for a holding midfielder and a central defender. He got one, but not the other, while also upgrading his full-back options with Joao Cancelo and Angelino.

After missing out on Jorginho last summer -- the Italian moved to Chelsea instead -- City finally found their long-term replacement for Fernandinho in Atletico Madrid's Rodri. At around €70m, the 23-year-old is the club's record buy and, judging by early performances against Liverpool and West Ham, it already looks like money well spent.

However, the search for a centre-back wasn't so successful. Leicester's Harry Maguire was on the list of possible replacements for captain Vincent Kompany -- who left for a player-manager role at former club Anderlecht -- but ultimately City would not match Man United's £80m offer.

Kompany was a huge character in the dressing room and almost impossible to replace, but one positive for Guardiola is that he will not have to squeeze too many extra games out of his other options. Kompany hasn't made more than 20 Premier League appearances since 2014-15 -- also the last time he played more than 30 games in all competitions -- and Aymeric Laporte, John Stones and Nicolas Otamendi will take on most of the extra workload now Eliaquim Mangala has been allowed to leave for Valencia.

It seems they are thin at the back, but Guardiola has also hinted that midfielder Fernandinho could also find himself at centre-back at times this season. City managed without an extra holding midfielder last season and it's unlikely their title defence will be dented too much after missing out on a centre-back. Still, expect the search for a new one to restart in 12 months' time. -- Rob Dawson

LIVERPOOL: A gamble on the future, especially at full-back

If anyone was surprised by Liverpool's minimal business in the market, they clearly haven't being paying attention to Jurgen Klopp's words or methodology. Stretching back to his days as manager of Borussia Dortmund, the German has craved squad continuity and while the Bundesliga side weren't equipped to fend off interest from the likes of Bayern Munich and Manchester United, a policy of player retention has been core at Anfield.

He believes in the power of collective development and generating improvement from within, so sporting director Michael Edwards' main responsibilities this summer have been to trim the squad and recruit gifted young players with lots of potential. Dutch defender Sepp van den Berg, 17, and Harvey Elliott, who became the youngest player to feature in the Premier League at 16 years and 30 days while at Fulham, have been drafted in as Liverpool consider the club's future.

The only first-team addition came in the form of goalkeeper Adrian on a free, who replaces Simon Mignolet as Alisson's deputy. The club were never going to go back in for Lyon's Nabil Fekir as they are well-stocked in central midfield but they did have designs on getting cover for Andy Robertson at left-back, before their first-choice target Lloyd Kelly joined Bournemouth instead.

The performances of youngster Yasser Larouci in preseason convinced Klopp not to spend on a position where James Milner and Joe Gomez can also deputise in -- though it is not ideal for either to start on that flank. On the other side, Ki-Jana Hoever -- one of the Academy's brightest prospects -- will develop into cover for Trent Alexander-Arnold, but Jordan Henderson, Fabinho, Milner and Joel Matip could also be used as a temporary fix at right-back.

All in all, the Merseysiders are confident their transfer policy will allow them to bring in game-changers in future and while it is a risk not to add greater quality in depth, it is a gamble Klopp is quite comfortable in taking. -- Melissa Reddy

TOTTENHAM: An Eriksen mess, defensive questions and a backup to Kane

Mauricio Pochettino has spoken of the "big mistake" made by the Premier League in enforcing the Aug. 8 transfer deadline which, the Spurs manager claims, places England's top clubs at a disadvantage against most of their European counterparts, who can continue to sign players until Sept. 2.

Pochettino's comments hinted at a realisation that his own rebuilding programme was incomplete, despite chairman Daniel Levy signing off the club's first purchases since January 2018.

The failure to push through a deal for Juventus forward Paulo Dybala saw Spurs fail to secure a replacement for Christian Eriksen, whose ongoing refusal to sign a new contract could see him leave on a free transfer next summer. And with Juan Foyth ruled out for at least a month with an ankle injury, amid doubts over Pochettino's faith in both Toby Alderweireld and Jan Vertonghen, Spurs have gone into the season with question marks over the centre of their defence.

Youngsters Jack Clarke (loaned back to Leeds) and Ryan Sessegnon have been signed for the long term, while Tanguy Ndombele and Giovani Lo Celso have added ready-made quality in midfield.

But having offloaded Vincent Janssen and Fernando Llorente since the end of last season, Spurs could once again find themselves short on attacking options if Harry Kane is sidelined through injury.

Allowing two centre-forwards to leave without replacing either of them is a risky strategy, even though the likes of Lucas Moura, Son Heung-Min and Dele Alli have all shown their ability to find the back of the net whenever Kane is absent. -- Mark Ogden

MAN UNITED: Midfield depth and a Lukaku replacement

United made significant improvements to their defence over the summer with the arrivals for Aaron Wan-Bissaka and Harry Maguire for a combined fee of £130m. But when the transfer window closed last week, there were still gaps in Ole Gunnar Solskjaer's squad and one in particular was emphasised during the 4-0 win over Chelsea on the opening weekend of the season.

Marouane Fellaini left Old Trafford in January, while Ander Herrera followed him at the end of last season, and it has left United short in midfield. Solskjaer will expect Andreas Pereira and Scott McTominay to play more games but it is still an area of the squad that looks short both on numbers and quality.

It will not have escaped United fans that even during a positive afternoon against Chelsea, there were significant chunks of the first half that were dominated by Frank Lampard's side and the scoreline at half-time would have been different had the visitors been more clinical.

After the departure of Romelu Lukaku to Inter Milan for €80m, there are also still question marks up front. Marcus Rashford and Anthony Martial have made a good start in trying to fill the void in terms of goals, with young Mason Greenwood ready to step up from the academy, but failing to replace the Belgian striker is still a risk for Solskjaer.

Rashford and Martial have both averaged close to a goal every four games during their United careers and Solskjaer is asking both to reach levels they have never managed before. Solskjaer has put his faith in young players in both midfield and up front and in the absence of new arrivals, United's success this season depends on it being repaid. -- Rob Dawson

ARSENAL: Defensive depth and consistency

While the £72m acquisition of Nicolas Pepe was the headline business for Arsenal this summer, their most vital trading occurred on deadline day with the signings of Kieran Tierney and David Luiz for less than half the Frenchmen's fee combined.

Over the past two league seasons, only Manchester City and Liverpool have outscored the Gunners, with their failings coming at the opposite end of the pitch. Arsenal shipped 51 goals in consecutive campaigns, rendering the addition of the experienced Luiz from rivals Chelsea for £8m at centre-back and Celtic's Tierney at £25m to solidify the left flank as imperative.

The loan move for Real Madrid's Dani Ceballos was inspired, as was the recruitment of highly rated young defender William Saliba, who will remain at Saint-Etienne on loan for 2019-20. The common thread with all these players is their stylistic suitability under manager Unai Emery and while there are lingering doubts as to whether Arsenal will have enough consistency and resolve without the ball to secure a Champions League spot, the team will not be short of goals or a fear factor for plenty of opposition managers.

The exit of Aaron Ramsey to Juventus on a free transfer early in the summer was a mess, while the drama surrounding former captain Laurent Koscielny's forced £4.6m move to Bordeaux was a shock they could have done without.

There is still a feeling that the defence's depth will struggle against the elite teams, with Ainsley Maitland-Niles still deputising for the injured Hector Bellerin at right-back and Calum Chambers thrown in at the deep end to prove himself as a centre-back. Any injury to No. 1 goalkeeper Bernd Leno would leave them with the inexperienced Emiliano Martinez, too. But on paper, and especially with their financial restrictions, Arsenal navigated the window as best they could. -- Melissa Reddy

CHELSEA: Transfer ban woes, but centre-back depth Chelsea's own doing

Having been hit with a two-window transfer ban by FIFA following an investigation into the signing of foreign players under the age of 18, Chelsea went into the summer knowing that they would not be able to add to their squad.

And with the realisation that Eden Hazard would be leaving for Real Madrid, the biggest challenge for the club was always going to be ensuring that Maurizio Sarri's successor as manager, Frank Lampard, would still have a competitive squad to take into the new campaign.

By striking a £57.6m deal for U.S. international Christian Pulisic in January -- with the Borussia Dortmund forward immediately loaned back to the German club for the remainder of the season -- Chelsea ensured they had a replacement for Hazard secured.

Mateo Kovacic's loan from Real Madrid also became a permanent deal in the summer and youngsters such as Tammy Abraham, Mason Mount and Fikayo Tomori returned from loan duty to bolster Lampard's options.

However, the departures of David Luiz to Arsenal (for £8m) and Gary Cahill to Crystal Palace (after being released) have left Chelsea without two experienced centre-backs, and that could become a problem during the campaign if the back four is hit by injuries. Kurt Zouma already highlighted the lack of depth with his poor performance in the 4-0 defeat to Man United this weekend.

Still, considering the restrictions placed upon the club by their transfer ban, Chelsea have emerged from the summer window in a healthier shape than their supporters may have feared.

Hazard is irreplaceable, despite Pulisic's potential, but the youngsters who have now been promoted to the first-team squad have the opportunity to stake their claim and save Chelsea more money in the market next summer. -- Mark Ogden
