Former Tottenham Hotspur manager Harry Redknapp has questioned whether Harry Kane would view a move to Manchester United as a step up.
Kane's future has been the subject of increasing debate in recent weeks following his comments that he will not stay at the club "for the sake of it", with United thought to be leading the race.
Real Madrid have also been credited with an interest in the England captain, and Redknapp believes that a move to one of the Spanish giants would be more attractive to Kane than joining the Red Devils.
"Harry Kane is a special player, he's the best centre-forward certainly in the Premier League and of his type I don't think there's a better centre-forward anywhere. Okay, he's not [Lionel] Messi, he's not [Cristiano] Ronaldo, but as a centre-forward that does what he does, there isn't anyone better," Redknapp told talkSPORT.
"He would be a great fit for Man United, he'd be a great fit for any team... but Man United at the moment are not better than Tottenham. I wouldn't say there's much between them, both teams are trying to get into the top four. Whether Real Madrid or Barcelona came in, he might fancy a move like that one day.
"But at the moment he belongs to Tottenham, and unless Jose Mourinho and Daniel Levy decide to will cash in if it's a crazy offer and rebuild the team with that money, unless Jose says, 'I've got three players here we can sign and build a better team with', then I'm sure he'll stay at Tottenham."
Kane has been Tottenham's top scorer in each of the last five seasons and is already third in the club's all-time list.
