TOP STORY: Wolves to move for Juve winger Costa
Juve boss Andrea Pirlo has reportedly told the Brazil international that he is not part of his plans this season, meaning he will be allowed to leave, with the Italian giants looking to freshen up their options on the wings.
10.48 BST: Manchester United have been linked with a move for Porto defender Alex Telles, but now The Sun claims they have a backup target.
Ajax's Nicolas Tagliafico is the man they could reportedly sign, as he's available for around €25m, while Telles would cost €40m despite being in the final year of his contract.
United are chasing a left-back to provide competition for Luke Shaw, but their primary desire is to sign a winger: namely, Borussia Dortmund's Jadon Sancho.

09.50 BST: Arsenal have made Lyon midfielder Houssem Aouar their top target this summer, as reported by ESPN earlier last month, but the Daily Telegraph says that "a Champions League club" will rival them for the Frenchman.
Arsenal's sporting director, Edu, has already called his Brazilian compatriot Juninho to enquire about Aouar, and mentioned midfielder Matteo Guendouzi as part of a potential swap deal, plus cash. Sources have told ESPN the meeting did not include details about a fee, though Lyon and Arsenal are due to talk more for a player valued around €50m.
The Athletic says the Gunners are considering sending Reiss Nelson out on loan this season in a bid to get the winger more playing time.
09.23 BST: SPORT have linked Barcelona defender Jean-Clair Todibo with an €18m (plus €5m in add-ons) move to Fulham.
Todibo, 20, signed for Barca last summer when his contract at Toulouse expired. He was sent on loan to Schalke last season but evidently isn't in the plans of new Barcelona Ronald Koeman, and will be allowed to leave.
09.02 BST: Luis Suarez's move to Atletico Madrid is back on after the striker's legal team reached an agreement in principle to terminate his contract with Barcelona , sources told ESPN's Sam Marsden and Moises Llorens.
A new deal had to be struck after Barca backpedalled on the original agreement made on Monday when it emerged Suarez was close to signing for Atletico.
The original terms would have allowed Suarez to leave for free in exchange for the Uruguay international giving up a percentage of the final year of his contracted salary at Camp Nou. In addition, he would not have been allowed to join certain clubs stipulated in the agreement.
Atletico did not feature among those clubs he could join, leading Barca to backtrack when it emerged their third-highest scorer of all time could potentially join a La Liga title rival for nothing.
Suarez, 33, was furious and sources told ESPN he was prepared to speak out on the issue, but that will not be necessary following further developments on Tuesday.

08.25 BST: Frank Lampard has admitted Callum Hudson-Odoi could leave Chelsea before the transfer window closes next month.
The 19-year-old will make his first start of the season on Wednesday night as the Blues host Barnsley in their EFL Cup third-round clash at Stamford Bridge (stream live on ESPN+ at 2:45 p.m. ET in U.S.) amid mounting speculation over his future.
Asked directly whether Hudson Odoi and Antonio Rudiger would stay at the club beyond the Oct. 5 deadline, Lampard said: "I'm going to skirt around that question. It remains to be seen.
"We're not in a period where the transfer window or market is acting like it has done in recent years in terms of how players move or what level they move at. The competitive games have just started. I'm very open to those conversations with the players as the next couple of weeks go on.
"My priority will always be making sure I maintain and keep the strongest squad I can for this club, but after that, of course, the individual conversations will happen within that. I will try and make sure I go into the season once the window shuts with the squad that I feel is healthy and competitive in a healthy way.
"At the moment we have Christian Pulisic injured, Hakim Ziyech injured. We played Timo Werner out wide the other day, but the absolute natural winger who is fit at the minute is Callum."
08.00 BST: Juventus have completed a loan deal to sign Alvaro Morata from Atletico Madrid, the club announced on Tuesday. Morata, 27, landed in Turin on Monday to finalise his move to re-join the Italian champions.
The agreement gives Juventus the right to definitively acquire Morata by the end of the 2020-2021 season for a transfer fee of €45m, which would be payable over three years. Juventus also have the right to extend the acquisition on a temporary basis until the end of the 2021-2022 season for a fee of €10m.
The striker enjoyed a successful loan spell at Juve during 2014-2016 where he scored 27 goals, including a strike in the 2015 Champions League final against Barcelona.
The Spain international won two Serie A titles and two Coppa Italia trophies in his two-year stint at the club.

PAPER TALK (by Danny Lewis)
Barcelona lead the way to sign Dest
Hot on the heels of ESPN's confirmation that Barcelona were swooping in late on Bayern Munich's pursuit of Ajax's Sergino Dest, Esport 3 now says the Catalans are in pole position to sign the USMNT right-back.
It is suggested that Barca are willing to pay €20m, with a further €5m being offered in add-ons.
Bayern have been heavily linked with Dest, but now Ronald Koeman's side have moved ahead in the race to sign him, despite Bayern raising their previous offer.
If the move comes to fruition, it will see the 19-year-old defender replace Nelson Semedo, who is set to join Wolves.
Fulham and Newcastle join Milik race
Napoli owner Aurelio De Laurentiis is said to be frustrated with both Milik and Roma due to the nature of their negotiations so far.
His current valuation of the Poland international is €25m, though that will reportedly need to be lowered if Fulham and Newcastle are able to meet Milik's wage demands.
- Inter Milan are willing to let Radja Nainggolan rejoin Cagliari now that Arturo Vidal has signed from Barcelona, reports Calciomercato. Antonio Conte was desperate for the Chile international to join his ranks and, now that has happened, Nainggolan will be allowed to go back to Cagliari on loan again.
- Leeds United are closing in on a move for Real Sociedad centre-back Diego Llorente, reports the Athletic. It is suggested he will be making a £20m move to join Marcelo Bielsa's side, after the club missed out on other options. This will make him the second centre-back they have signed this window, after Robin Koch joined from Freiburg.
