Matthew Upson has been impressed by new West Ham signing Valon Behrami.

"He was very good [against Peterborough]," Upson told whufc.com. "Valon has come in from Italy. He has done a lot of tactical work in training and in the game so he knows how to keep a line and position himself. It is good that Lucas is able to push across to the left and do well. With George not involved at the moment, we may need to call upon him to do a job there so it is nice to get used to that pattern in the back four."
