Mauricio Pochettino has once again refused to offer any promises that he will be Tottenham Hotspur manager next season and claimed that Virgil van Dijk has been a £75million bargain for Liverpool.

Manchester United this week confirmed the permanent appointment of Ole Gunnar Solskjaer, ending their interest in Pochettino, after Real Madrid re-appointed Zinedine Zidane.

Pochettino has reiterated his commitment to Spurs, but explained why he could not give supporters any assurances over his future.

Asked whether he will definitely be Tottenham manager next season, Pochettino said: “It’s the same question as two months ago, three months ago. It does not depend only on me, it’s about Daniel (Levy) too.

“Of course, I know he is happy with me and that is what he is telling me. But Tottenham is bigger than one person. Tottenham is bigger than one player, Tottenham is bigger than everything.

“Always, I need to fight every day to keep my position. That doesn’t mean I am not comfortable. Always I tell Jesus Perez (Pochettno’s assistant), ‘we need to think that maybe tomorrow, if we don’t care about our position, we can go away quick’.

“Football changes very quick. It’s difficult to say ‘I am now happy and sure I will be here next season’. If I said that and something wrong happened and I’m not here, then you say ‘oh Pochettino said he will be here and now he’s not here’.

“In my mind, always I am living like today can be the last day, tomorrow can be the last day. That is my philosophy. A player can say ‘ok I will be here for five years’ but a manager no, because he can be sacked tomorrow.

“Look at what happened at Real Madrid. Zidane said ‘I go’, then two managers and not even the end of the season, and he’s back. Who believed that? That is why, in football, everything that today is white, tomorrow is black and then white again. Things can turn so quick.”

Tottenham travel to Anfield to face Liverpool on Sunday, having not won any of their last four Premier League games. And Pochettino believes central defender Van Dijk has turned the Reds into realistic title contenders.

“When a team like Liverpool needed to improve their team in a certain area, people said it was crazy to pay £75m for a centre-back,” said Pochettino. “But Liverpool were right.

“They picked Van Dijk, because at that moment they believed he was the best centre-back in England who could make them better, and they were right. The people who believed other things have now been shown that Liverpool were right.

“Some people said ‘Why would you pay £75m for a centre-back?’ But if you are going to sign the player who is going to improve your team, then it is not a lot of money. Because to win a Champions League or a Premier League, it is cheaper to spend this type of money.

“Always there are different opinions, but for me today if he is not the best he is one of the best centre-backs in the world.”
