Arsène Wenger admits Manchester City’s home advantage may pay dividends in Monday night’s crucial derby. Manchester United head to the Etihad Stadium three points clear of their local rivals with just three matches of the season remaining. City have a stronger goal difference, however, and Wenger believes a tight affair may be decided by Roberto Mancini’s side’s home comforts.“I don\'t know who will win it but I agree that City have the advantage,” said the Frenchman. “If you want to be champions you have to win against your main opponents at home. “They have the advantage to win at home, to play their game at home. You would say that it is an advantage. If you ask Manchester United if they would prefer to play at Old Trafford then they would say yes. “City still have difficult games left. But they have an unexpected chance, they were completely out of the race. You would think this time that the momentum goes a little bit for them. “But Manchester United can always respond. It will be interesting to watch and for me it is very difficult to predict who will win.”
