Tottenham hero Darren Anderton can see Harry Kane only leaving for one of Spain's big two.
Spurs lost their first-choice right-back, Kyle Walker, this summer while Danny Rose has gone public with his own unrest and the likes of Eric Dier are reportedly open to leaving.
"I think most players need to have competition to improve their game, but I don't think Kane needs it," Anderton told sportingbet.com.
"He's young and hungry and I think the fact he went out on loan so often to lower league clubs when he was younger, it's really toughened him up – especially mentally as he's got so much belief in his ability and desire to be at the top. He's a dream for a manager as he's always got his foot on the pedal.
"Harry's the top man at the club and the one player they can't afford to lose. I think he loves the club and wouldn't want to force a move, but if Real Madrid or Barcelona come knocking, he could go."
