Mauricio Pochettino insists he is not already planning for life without Toby Alderweireld.
Alderweireld faces an uncertain future at Tottenham, with his contract expiring in summer 2019.
Tottenham can automatically extend his current deal by one year, but doing so would activate a release clause of around £25million.
Barcelona and Manchester United are thought to be monitoring the situation, but Tottenham have fared well without their Belgian centre-half in the meantime.
Eric Dier and Davinson Sanchez started at the heart of the defence and kept a clean sheet in the victory over Crystal Palace on Sunday, with Sanchez seen by many as Alderweireld’s natural successor.
Asked whether he started both Dier and Sanchez as a way of preparing for Alderweireld’s eventual departure, Pochettino replied: “No, no, no.
“I think it is important to say that all the players are important for me.
“Toby is such an important player for us. Like always I told you in these nearly four years, for me the most important thing is the squad. For me the most important thing is the team and of course players are important, but the collective is so important because when you have some problems you need to win games.
“If all the players feel important and capable to perform in situations like with the other game, with Eric Dier and Davinson, I think it is a big benefit for the team.
“But I think all the players are important.
“We think about today, tomorrow and the next game. We’re happy with all the squad, all the players.”
