Man Utd 3-2 Fulham

A very exciting game as United manage to beat Fulham at Old Trafford by 3-2. After going behind in the 2nd minute, an amazing goal from Robin Van Persie (RVP's first United goal) got United back on track. Then Kagawa (first competitive goal for United) scored an easy goal, and Rafael scored shortly after. Fulham managed to score another goal, but it didn't end up effecting the result. Nani and Rooney started on the bench after having pretty terrible games against Everton. However, Rooney came on towards the end, only to get injured, and it now looks like he could be out for 1-2 months. Hopefully he can come back better then ever.
What did you guys think of this game? Will Rooney come back stronger? Does United still need to sign any players? Let me know!
