Chelsea defender Branislav Ivanovic admits there's been no talk of changing their play from manager Andre Villas-Boas after recent results.

Some have questioned whether Villas-Boas' attacking philosophy has made Chelsea too open.

Ivanovic said: "He hasn't asked us to change something defensively.

"Defence is simple. You have to be better than your opponent, to show more wish to win every tackle in every game.

"Of course we are playing more attacking football, but to lose a game 5-3 at home, it's a defensively poor game."
