Tottenham boss Jose Mourinho admits he wants more from Tanguy Ndombele.
Mourinho says although he is much happier now with club-record signing Ndombele, the manager feels the 23-year-old French midfielder can still offer more.
"In this moment, I'm happy," he said. "His potential is huge. So is he doing well? Yes. Am I happy with him? Yes, I'm happy with him, but I still think that he can do more. He can be fitter, he can give us 90 minutes without problems. He can be better than he is.
"Of course he's happy because he's playing, I'm happy because he's doing important things. I see the future probably better because as I was saying, his potential is great. But I have to try to educate players, I have to try to give my best.
"I'm not here to be their best friend, I'm here to be their coach above all, and I will never be different to what I am. So when I'm not happy, I'm not happy. At this moment I'm very happy with him."
