Tottenham chairman Daniel Levy insists the club will not sell any player they don't want to leave in the summer.
"I'm 100 per cent confident. Every single player that we want to keep, I can assure you will be playing for Tottenham Hotspur next season," he told Sky Sports News.
"Mauricio's strategy has always been that if an opportunity arises that he thinks can improve the squad then we will need to look at it, but January is always a very difficult window."
