4. The Pressure
From the minute Van Persie signed, he has been toted as the difference between last season's 2nd place finish and a title win this season for United. Forums, managers and journalists alike have flocked to welcome Van Persie as the missing piece for United. Factually, he may not be that, The Red Devils midfield and defence is weaker than it has been in years, particularly when compared to their rivals Manchester City. With the extreme amount of pressure on Van Persie to be the big difference, he may suffer a crisis in confidence if it begins to look like they might come up short and if he is not scoring enough goals. As we saw in Euro 2012, RVP suffers , like many footballers, when so much is expected of him.
