Chelsea boss Andre Villas-Boas says he's to blame for their recent form slump.

The Portuguese insists he is the only one who should be blamed for the slump which has seen the team drop to fifth in the Barclays Premier League.

He said: "There is one person who takes responsibility. That is myself. The players don't have to take it and they shouldn't."

Chelsea's hopes of climbing the league will not be helped by claims of in-fighting, but Villas-Boas insists he has no problem with the senior players who are reportedly unhappy with his management and tactics.

When asked about his relationship with the likes of Ashley Cole and Frank Lampard, Villas-Boas said: "It is very good. There are no problems."
