Tottenham boss Mauricio Pochettino has refused to comment on speculation over the future of Toby Alderweireld.
The Times reported on Friday that contract talks with the defender have reached stalemate and that Spurs are ready to sell him in the summer.
The club are reported to be unwilling to match Alderweireld’s wage demands.
Asked at a press conference, Pochettino said: “I am not involved in negotiation. I never talk about rumours, what the media say or what happens around the club.
“It is not my job and I cannot say nothing about that.”
Meanwhile, Pochettino has hailed Mousa Dembele, declaring that the Belgian deserves to be regarded as a top player.
“I can only talk about him because I know very well him after nearly four years,” Pochettino said.
“In my book, I put him next to Ronaldinho, Maradona, Okocha – players that I was lucky to play with.
“I think for me he is one of the unbelievable talents in the history of football.
“Of course always for him it was difficult to get fit – he always fits with his fitness.
“But now he is in an amazing moment and for me he deserves all the praises that people are giving him.”
