Tottenham boss Ange Postecoglou praised captain Heung-min Son after victory over Luton.

Son struck a late winner as Spurs triumphed 2-1.

Postecoglou said: "I think the thing about Sonny is that irrespective of opposition or whatever game it is, he has this really high level of expectation on himself to be the best he can be all the time.

"It's very hard to be like that. It's a lot easier to try and get comfortable in the state of being as a person or as a player because he's done so much already. But he wants to maintain the highest possible standards whenever he plays, and when you see that with his football, his efforts, his leadership now so it's all encompassing.

"Look, he's been a brilliant footballer for this club for a long time and hopefully for many years to come, and again I thought he was really unlucky with a couple of chances and some good saves. But when we needed him he was there and got the job done."
