Kane left Spurs earlier this month to join Bayern Munich and as a result, the North London club are without a threat in front of goal. 

In an attempt to solve this problem, Berbatov has suggsted that out of favour Chelsea striker Romelu Lukaku should swap Stamford Bridge for the Tottenham Hotspur Stadium. 

"Will Spurs invest any of the Kane money to buy a replacement? I think they will," Berbatov told Betfair. 

"No one can replace Kane right now, and I don't think he can ever be replaced, but Spurs need to find a goalscorer.

"Richarlison has the opportunity to show he's good enough but Spurs need to buy someone else too.

"I heard that Romelu Lukaku was a potential candidate. He's an interesting option. If the problems he's been having at his former clubs are resolved, then why not?

"He's underrated. He can score goals wherever he goes. He has to play because if he doesn't, he won't be happy and there will be problems for Spurs."

Lukaku went out on loan to Inter Milan last season where he made 25 appearances and scored 10 goals.
