Brilliant Aguero, weak Arsenal, all-round Lukaku, slumping West Brom

WATCH: Paul Mariner's damning indictment of Arsenal (4:10)

Former Arsenal striker Paul Mariner slams Arsene Wenger's team selection and the Gunners' lack of urgency in their Carabao Cup final defeat to Man City. (4:10)

Rounding up the best and worst of the weekend action in the Carabao Cup final and Premier League.

Goal of the weekend

It probably shouldn't have been allowed -- Shkodran Mustafi's defending was horrendously weak, but that doesn't mean Sergio Aguero didn't foul him -- but Manchester City's Carabao Cup final win over Arsenal was set up by their record scorer, who produced the most delicate of lobs. To be honest, it was so beautiful that is made mere "rules" feel churlish.

Parody performance of the weekend

There isn't much point launching into another detailed post-mortem of an Arsenal defeat, because it will read essentially the same as before. But if they have any dignity then they'll be embarrassed by their performance at Wembley, where Man City strolled to an easy victory without having to be near their brilliant peak.

Arsenal didn't stop trying, or fail to put in enough effort, they're just weak. Weak, thanks to years of decline, of disappointments like this one and of not being pushed for anything more. Nobody should be surprised by what happened.

Troll of the weekend

When Arsene Wenger asked the fourth official why the "correct" amount of injury-time had not been added, the reply was cutting: "Why do you want more time?" And yet there was a more serious aspect to the whole business, specifically that Wenger was bringing up the issue at all. If he genuinely thinks that an extra minute or so would have made any difference to the result, then that's a far bigger concern for Arsenal than errant timekeeping.

Performance of the weekend

For all the discussion about Romelu Lukaku's record in big games, he has been playing well for a few weeks. He was one of the few points of interest from Manchester United's grim 0-0 draw with Sevilla and he converted that into something more tangible against Chelsea.

His goal might have looked simple but it was more difficult than it seemed, if only because he was being fouled at the time of his finish. He also exhibited terrific all-round play, but perhaps more impressive was the assist for Jesse Lingard's winner, a perfect cross that the United substitute only needed to divert home.

Worst substitution of the weekend

Sometimes honesty isn't the best policy. When Chelsea manager Antonio Conte was asked why he took Eden Hazard off vs. Man United with the score still at 1-1, he answered that it was a tactical move. While we don't endorse lying, when said "tactical" decision had been exposed as one that quite obviously did not work, surely the best policy is to invent an injury, or claim the player was fatigued.

Unluckiest team of the weekend

You must have some sympathy for Crystal Palace. Going into Sunday's 1-0 defeat to Tottenham they had 12 senior players out injured, only to lose James Tomkins during the game. While he will never be the most vital player for any Premier League team, at least he was fit. Palace's revival under Roy Hodgson has stalled and it won't get going again until a few of their absentees return.

Inevitability of the weekend

Tomkins' replacement Damien Delaney probably thought he'd done a reasonable job of marking Harry Kane for Tottenham's late corner at Selhurst Park. He was touch tight and sticking to his man but, as the ball sailed across and Delaney briefly faced the wrong way, Tottenham's phenomenal talisman pounced to loop a header into the net and seal three points for Spurs.

Time running out of the weekend

Before Alan Pardew took charge as manager, West Brom gathered 12 points from 14 matches and were 17th in the table; in the 14 games under his management they've managed just eight, have sunk to the bottom of the table and are seven points shy of safety. On Saturday, they lost at home to Huddersfield.

"I hope to free up this team a little bit more if I can," Pardew said upon his appointment in November. "That's easier said than done because we need to start winning games to do that."

From their remaining 10 games West Brom probably need to win at least four -- one more than they've managed so far this season -- to stand any chance of survival. There is talk that Pardew could be sacked but, in some respects, it doesn't matter; miracles are required for the club to stay up

Low-key performance of the weekend

Left-back has been a problem position at Liverpool for many years -- sub-standard specialists, plucky fill-ins and expensive liabilities have all had a go -- but Andrew Robertson looks here to stay. He nearly didn't make it as a professional and, at one stage, considered a career in teaching. Now he looks like he'll be a Liverpool fixture for years.

Second-worst goalkeeping error of the weekend

Though he later made a superb save to deny Riyad Mahrez a winner, Jack Butland will presumably be somewhat embarrassed after his mistake gifted Leicester a point against Stoke. But at least he isn't this guy.
