Aston Villa striker Darren Bent admits he doesn't know what he did wrong after being frozen out by manager Paul Lambert this season.

Bent says he hasn't spoken to Lambert about his situation due to Villa's relegation battle.

"I've not been to see the manager," said Bent. "It's been a difficult situation anyway, fighting relegation. The last thing I want to do is go in, kicking and screaming. It's about the team, after all, not one individual.

"But I'm at a loss to know where it all started to deteriorate. I know I've had a few injuries this season and stuff but at the same time I can't pinpoint where it all went wrong.

"I'm not giving it any less than 100 per cent. Sometimes it just goes like that."
