MANCHESTER United's ob-session with the European Cup could allow Arsenal to snatch the Premier League title, according to the London club's manager Arsene Wenger. 'Maybe I am a little crazy but I honestly think we can do it,' said the Frenchman. Second-placed Arsenal trail the champions by nine points with three games in hand. The two meet at Old Trafford tomorrow and Wenger insists his team can still prove the bookmakers wrong. They stopped taking bets on the title race a week ago but reopened the book after the results in midweek. Arsenal travelled to Wimbledon on Wednesday night for their eighth successive London derby, winning 1-0 with a Christophe Wreh goal while United were held to a 1-1 draw at West Ham and Chelsea hammered Crystal palace 6-2. Wenger says United will be thinking more of his former club Monaco, their European Cup quarter-final opponents on Wednesday. The first leg 10 days ago ended 0-0. 'United's main task will be dealing with Monaco but that will not be easy for them,' added Wenger. 'Over the years Monaco have proved they have the strength and resilience to win important away ties after being held in the first leg.' Wenger is confident that even if Arsenal had failed to beat Wimbledon they would not be out of the race. ' Whatever happens I think 73 points could win the title and there are few teams capable of that,' Wenger said. United manager Alex Ferguson admitted the tension of European football was taking its toll but added: 'We have got a chance of getting into the semi-final of the European Cup and we have got to take that.'
