David Moyes has suffered another big blow in his first season as Manchester United manager after his side were dumped out of the FA Cup by losing at home to Swansea.
Wilfried Bony's late header sealed a famous 2-1 upset for the Swans at Old Trafford after Javier Hernandez had levelled Wayne Routledge's early goal for the away team.
United, 11-time winners in the competition, ended the Third Round game with 10 men following substitute Fabio's red card.
The result leaves the Champions League and League Cup as the only realistic chances of trophy success for Moyes' men with United trailing Premier League leaders Arsenal by 11 points.
Arsenal manager Arsene Wenger said Theo Walcott's gesture was in response to coins thrown by Tottenham fans and that his actions were not aggressive but "smiley".
Guardian reporter Dan Taylor recounted:

More from Wenger on Walcott's gesture: "I've seen the pictures afterwards - it does not even look aggressive, it's smiley."
AP reporter Rob Harris said Tottenham manager Tim Sherwood put Walcott's gesture down to "a bit of banter".

Arsenal striker Theo Walcott infuriated Tottenham fans by making a 2-0 gesture towards them as he was stretchered off the pitch towards the end of his side's FA Cup third round win.
Goals from Santi Cazorla and Tomas Rosicky sealed the win for the home side.
Walcott was carried from the field after appearing to injure his knee during a challenge late in the game.
Asked about the incident after the match, Arsenal manager Arsene Wenger said: "The doctors said to me the coins were raining over his head [from the away fans] and that is why."
Aston Villa manager Paul Lambert no longer has the distraction of FA Cup fixtures after his Premier League side suffered a shock 2-1 home defeat to League One's Sheffield United.
Lambert sparked a debate in football after claiming that most top-flight bosses would prefer to do without the fabled cup competition.
The Villans had been heading for an unwelcome Third Round replay after Lambert's sub Nicklas Helenius levelled in the 75th minute but a late goal from United's Ryan Flynn secured the upset win.
Two goals from substitutes secured a win for Ole Gunnar Solksjaer in his first game as manager of Cardiff City.
The Welsh side were a goal down in their FA Cup tie at Newcastle United before strikes from Craig Noone and Fraizer Campbell, both off the bench, saw Solksjaer's men through to the fourth round.
The Norwegian was known for his super-sub heroics during his 11 years as a Manchester United forward, most notably a stoppage-time winner in the final of the 1999 Champions League final.
Everton manager Roberto Martinez, who led Wigan to FA Cup glory last season, has said winning the fabled competition remains on a par with success in the Premier League.
"It’s like asking if you prefer mum or dad," he told reporters when asked to choose between them ahead of Everton's third round match against QPR tomorrow.
A debate about the competitions was sparked by Aston Villa boss Paul Lambert who said top-flight clubs could "probably" do without the cup at a stage in the season when safety or a top-four place was the priority.
The Everton boss Roberto Martinez has declared "the FA Cup is unique" after Aston Villa boss Paul Lambert said the majority of Premier League sides saw the competition as a "distraction":

"It’s like asking if you prefer mum or dad." Martinez says it's impossible to choose between FA Cup or league success:http://t.co/vKEJxRF12w
Arsenal manager Arsene Wenger has dismissed the suggestion that top-flight clubs could do without the FA Cup, saying that he would like to win the famous old trophy once again.
Aston Villa boss Paul Lambert was asked yesterday whether the domestic cup was something Premier League clubs could do without and he told the BBC: "If they were being honest, they probably would do."
But Wenger claimed the FA Cup presented an opportunity for Arsenal to end their eight-year trophy drought.
He said: "I don't believe that at all. We have not won trophies for a long time, it is an opportunity that we want to take that we consider.
"On top of that we have afterwards nine days until the next Premier League game, we can give absolutely everything in this game."
Arsenal will play North London rivals Tottenham in the FA Cup third round, which you can watch live this Saturday at 5.15pm on ITV or on the ITV Football website.
