Arsenal's annual collapse is becoming such a fixture in the English football calendar that the F.A. might have to start penciling in dates for it to happen like they do with the later rounds of the F.A. Cup. The last few weeks have seen Arsene Wenger's men stumble on all fronts - held by Hull, beaten by Barcelona and then mauled my Manchester United, things got worse in midweek when they were savaged by Swansea. The last two league games were the perfect time for Arsenal to make a statement of intent. They were limp against a youthful, injury-hit United and error-prone against relegation battling Swansea. That result was made to look even worse by the fact that title rivals Tottenham and Manchester City both lost and pace setters Leicester City were held to a draw. Arsenal's travails as the Premier League season reaches its climax have led many pundits, ex-players and fans to say that the coming summer is the time for Wenger to either jump or be pushed. He has been in the Arsenal dugout for two decades and the worry is his departure could lead to a state of flux like that experienced at Old Trafford when Sir Alex Ferguson called it a day. If Arsenal once again fail to win the title - which looks a near certainty now - and those at the club decide it's time for a change, who could take Wenger's place in the Emirates Stadium dugout?
