Mauricio Pochettino refused to rule out managing Real Madrid in the future.

Pochettino joined Spurs as manager in 2014 and turns 46 in March.

"I am so clear: I am never going to be manager of Barcelona or Arsenal because I am so identified with Tottenham and Espanyol," Pochettino said.

"I grew up in Newell's Old Boys and will never manage Rosario Central. I prefer to work on my farm in Argentina than in some places.

"But my commitment is massive in this club. I am working like I am going to be here forever. But in the end, it is like the players, you never know what is going to happen in football.

"Tomorrow Daniel [Levy, the Tottenham chairman] could have a bad night and say, 'Oh I am going to sack Mauricio.' And then I look stupid saying I am not going to work in one place or another.

"You never know in football. That is the problem. It is a very unstable situation."
