Ajax tell Tottenham target Davinson Sanchez they do not want to sell

Davinson Sanchez impressed against Manchester United in the Europa League

Ajax have told Sky Sports News that they have informed Tottenham target Davinson Sanchez they do not want to sell him this summer.

Sky Sports News understands Spurs are interested in signing the 21-year-old centre-back but reports that a deal is close to being agreed are premature.

Sanchez was left out of the Dutch side's Eredivisie opener on Saturday because manager Marcel Keizer and sporting director Marc Overmars felt he was not focused enough amid the uncertainty.

Overmars has also confirmed to Dutch newspaper De Telegraaf that Ajax have offered him an improved contract after just one successful year at the club.

An Ajax spokesperson told Sky Sports News on Sunday: "Last year Sanchez signed a five-year contract and we don't want to let him go.

"That's what (sporting director) Marc Overmars has told the player and his agents. He is a great player who is very important for us. Next to that, we never comment on rumours regarding transfers."

Spurs have been in the market for a new centre-half and pulled out of negotiations to sign Argentinian Juan Foyth from Estudiantes because Mauricio Pochettino felt they were demanding too much for the youngster.

Pochettino was pleased with is side's performance but said they still need to bring in more players "to refresh and add energy and competition to the squad."
