Mousa Dembele was delighted for Tottenham matchwinner Erik Lamela after victory at West Ham.

Lamela struck the only goal of the game on Saturday.

"It's incredible, he's helping us a lot with goals, his quality, rhythm of work, all we can ask of an important player like him," said Dembele.

"Everybody knows that he has a strong mentality and that's why he has improved a lot and we see that he's so important to us and we've always known it.

"He's shown he's very important for us."
