We analyse the key moments from United's cup clash with Swansea...
The match United had the better of large swathes of this cup clash and, having cancelled out Wayne Routledge's opener through Javier Hernandez, the Reds seemed primed to go on and win it. But failing to truly test the visiting defence any further, especially after half-time, came back to haunt David Moyes' men as Wilfried Bony popped up with a late winner. Fabio's sending off just a few minutes after he replaced Rio Ferdinand only compounded an afternoon to forget.
The goal Chicharito's predatory strike was the perfect riposte to the visitors' opener against the run of play. Alex Büttner had already whipped in a testing corner and cross from the right, and the Dutchman's pin-point delivery from his usual station on the left gave his Mexican team-mate a chance he seized upon with relish.
Star men Büttner took his chance from a rare start to show off his talents, delivering several dangerous crosses as well as the ball that set up Chicha's goal. He also timed a tackle on Bony well with the game poised at 1-1, and proved he is a worthy understudy to Patrice Evra.
Sub-plots If Wayne Rooney and Robin van Persie's respective knocks need more rest, then Chicha and Danny Welbeck have shown that they provide a goal threat, but taking chances was United's downfall here and as a team the Reds must respond in Tuesday's League Cup semi-final first leg at Sunderland.
Opposition Swansea's passing and movement is excellent, as you might expect of a club boasting its fair share of Spanish players and with Michael Laudrup in charge. They also boast a fearlessness, which probably contributed to them going in front here. Despite a precarious league position, they're undefeated having started in a winning position this term, so their dangerous early lead proved to be tellingly prophetic.
