Chelsea management were disappointed with Billy Knott after his red card in defeat to West Ham United U18.

The left-back has been impressive this season, but saw red for dissent in the 3-1 loss.

Chelsea coach Dermot Drummy revealed to chelseafc.com: "Billy Knott was against his old club and I spoke to him before the game about the need to keep composed.

"He has to learn from his errors. We don't know if it is a one or three-match ban yet and with the FA Youth Cup coming up, he could learn the hard way."
