Tottenham hero Dimitar Berbatov says Harry Kane will be ­questioning his future at Spurs.

Kane has cut an increasingly ­frustrated figure of late – remarking that the club never seems to learn ­lessons and move forward.

Berbatov, speaking in his role as a Betfair ambassador, told the Mirror: “Harry is scoring goals, but Spurs aren't performing well. That's a tough situation and I've been there before myself.

“Now he's on an ­international break, what happens if he doesn't get the results he wants with England? He won't feel good about that.

“I think he will be fine, but I do ­question if he is out of his comfort zone. Is he asking the right questions of ­himself?

“Yes, he's starting for the team, he's playing regularly and still scoring goals. But is that enough? Is he going to grow and develop constantly if he wants to be among the very best of the very best."
