Chelsea boss Andre Villas-Boas admits West Bromwich Albion were superior in almost every position for yesterday's shock defeat.

Villas-Boas conceded his side were second best in all departments with only Ashley Cole, who suffered a severely bruised ankle in the latter part of the game, escaping criticism.

He said: "We have a defeat which is badly taken because we were very poor on the day. We have to improve. This is bad. This defeat cannot be well taken.

"The only player at an outstanding level today was Ashley Cole. The rest of us all under-performed from management to the rest of the players.

"Full credit to West Brom but we weren't good enough on the day. They won every first and second ball and were far superior to us. It's a big disappointment and a poor, poor display.

"We had an edge for the first 10 minutes when we had a couple of chances and a goal then would have given us extra motivation and drive.

"But West Brom also had chances, created lots of problems, there was good intensity in their game and we weren't good enough."
