For Man U: Ferdinand,Van Nistelrooy will be out.And ManU has the Champions League qualifier to concentrate.I won't be surprised if Fergie rests a couple of key players.Though I expect Alan Smith to start.
For Arsenal:Viera,Henry may not play because of injuries.It'll most probably be a Bergkamp,Reyes strike partnership.No champions League duties for Arsenal but
Wenger has already proclaim that he will not be fielding his strongest sideMy prediction: Man U won't win in 90 mins.It'll be either an Arsenal win or draw.
My final decision tmr.
