O'Neill Wolves draw

Sunderland boss Martin O'Neill says the number of games his side have played is catching up with them after a lethargic performance in their 0-0 draw against Wolves.

O'Neill admits his team did not deserve to beat Wolves and says they must do more to keep hold of possession.

Wolves came close to snatching victory at the Stadium of Light when striker Stephen Fletcher's header was brilliantly saved by keeper Simon Mignolet.
