Ex-Spurs goalkeeper Paul Robinson thinks the club need to sign Barcelona defender Samuel Umtiti.
Barca are desperate to raise funds this summer and Umtiti could be surplus to requirements.
And with Spurs likely losing Jan Vertonghen on a free transfer, Robinson says Jose Mourinho should target the World Cup winner.
"Umtiti is what they need." Robinson told Football Insider.
"Vertonghen has not been himself. Whether it has been the contract, but it looks like he has always had it in mind to leave.
"He has looked disheartened at times, you could see it in his body language. He has not been himself.
"Someone like Umtiti, who is only 26, would be ideal if Vertonghen is leaving.
"If he does leave it is a position they will have to look at. I suspect they will strengthen with more than one but Umtiti fits the bill. He would be a great signing."
