Billy is eligable, his suspension is done after Hull.
Pienaar won´t play, not a chance. He´s been out 2 months and will play in the reserves first.
Moyes will play a packed midfield with Heitinga and probably Neville aswell. Then the usuall suspects of Cahill and probably Osman on the right. Negative and dreadfull as usuall. Billy will be the one bright spot.
If I was Moyes though, I´d bench Cahill and play 4-4-2 with Fellaini behind Saha and Yak, and Rodwell, Hetinga and Billy behind them. Cahill just isn´t doing it this season.
