Chelsea midfielder Frank Lampard has admitted frustration over his treatment by manager Andre Villas-Boas.

Lampard has been in and out of the Chelsea side all season but suggested he should have been given more game time during the five-match winless run he helped end on Saturday.

"I've been here a long time, I'm 33, I'm realistic," he said after scoring the 150th league goal of his career in the Blues' Barclays Premier League victory over Bolton.

"It doesn't mean I want to play every game but, if I sit on the bench, I want to see Chelsea win.

"I'm sure we're all frustrated at the minute, everyone who's involved, especially people who have got Chelsea in their hearts, who have been here a long time and want to see us performing as we should do."

He added: "The only way we can push on from now and secure Champions League football next year, potentially move through in the FA Cup and the Champions League this year, is to be positive.

"It's in the club's interest. It's not about any one individual here and negative things can take the shine off it."
