Spurs are negotiating with Manchester City about a loan signing for the striker.
"I played against him when I was young [in France] so I know him well,'' the Tottenham Hotspur left-back said. "He is a little bit like Peter Crouch but with more mobility. He will find a good complicity with Defoe because Jermain is used to playing with that style of player. We saw what he did against us in Madrid [on loan at Real] last season, so I am sure he will help us.
"If the manager signs him it's not to finish fifth or sixth. He's a player from one of the big four and if we get a player from one of those clubs, it's for Tottenham to finish in the big four. We know his reputation but we don't care about that if he scores many goals."
