Arsenal boss Unai Emery has warned Tottenham counterpart Mauricio Pochettino about a move to Manchester United.

Emery is good friends with Pochettino — who he comes up against tonight in their Carabao Cup quarter-final — after the pair managed in Spain at the same time.

And the former Sevilla chief believes Poch might be better off staying put.

When asked if the Argentine would make a good United boss, Emery said: “He's very happy at Tottenham.

“He's coaching a very big team with very big players. They are in the Champions League and are also in a better position in the Premier League than Manchester United.

“His performance at Tottenham is very big. I don't know if he's thinking to change for another club but I am looking at him with a very big commitment to Tottenham and he's creating a good performance, a good idea at Tottenham. Tottenham improved a lot with him."
