Issa Diop has welcomed former France U21 teammate Sebastien Haller to West Ham.

Having both played alongside and marked his fellow countryman in training, centre-back Diop is confident West Ham have signed a striker with all the attributes needed to make a big impact in Claret and Blue.

“Sebastien is a very good player, he is very strong and he has very good technique and I hope he is going to score a lot of goals for us!" said the defender to whufc.com.

“I played alongside him for France U21s and we had a few games together and also many training sessions, so I know how difficult he is to challenge because he is very tall and very powerful.

“He uses his body very well to make things tough for the defenders, so I hope he can do that for us."
