Darren Bent admits he's still frustrated at Aston Villa.

Bent returned to the starting line-up for the 1-0 defeat at Fulham on Saturday, but was subbed for Christian Benteke on 75 minutes.

"Obviously any player who values himself wants to play week in, week out," said the former Spurs and Sunderland hitman.

"When you start playing rotation systems it is difficult to find a rhythm - especially when you are a front man.

"But it is the manager's decision and we live by that and you have to keep working hard in training and showing him that you want to play."
