William Gallas has been impressed by new Tottenham teammate Moussa Dembele.

The defender believes Dembele can make a big difference to the team.

Gallas told tottenhamhotspur.com: "For his first game, he came on in the second half and that will be good for his confidence. He helped us a lot.

"He's a good player, he has a lot of quality, he's still young and it will be good for everyone to play with him."
