Nani, Nasri or Van der Vaart, but the next few month's could change that, if RvP keeps scoring like he is, he might be in for a late shout and if Rooney takes confidence from his wonder-goal he could really push himself up there.
I know Berba has 19 goals in 23 matches....but he has only actually scored in 9 of those matches. Thin the goal to game ratio really flatters him. His performances have been good this year, but I'd also say Nani and Vidic have been more important this season.
VDV, vidic, and Adams have all played well. As have both Nasri and Berba.
Think Van Persie could be up on this list by end of the season, if he doesnt get injured again.
But best player so far for me has to be Heskey
i agree with tevez, he has pretty much carried city this year. maybe johnson for birmingham? theres a reason st andrews has seen the least goals in the prem.
