Chelsea must be unified - Frank Lampard

Chelsea midfielder Frank Lampard says the Blues must be unified if they are to challenge for honours this season.

Lampard scored his side's winner in the 2-1 victory over Wolves at Molineux . The visitors celebrated their first goal, scored by Ramires, by running to their manager Andre Villas-Boas in a show of support for the Portuguese.

The match-winner says there is no unrest behind the scenes at Stamford Bridge and calls on the team's senior players to step up and respond to the challenge of competing with their Premier League rivals.

Lampard also admitted he has found it frustrating not being a regular starter under manager Andre Villas-Boas, especially as the team have not been performing as well as he believes they should.
