Crystal Palace are in advanced talks to sign Tottenham defender Kyle Walker-Peters, Football Insider understands.

The south London club are working on a deal to take the right-back to Selhurst Park after he failed to make an impression under new Spurs boss Jose Mourinho.

A Palace source has told Football Insider that the club are increasingly confident of signing Walker-Peters, 22, on loan for the rest of the season.

Discussions have also taken place about including an option to sign him permanently at the end of the campaign.

That has not yet been agreed, but it appears that the Spurs academy product is set for the short trip across London to ignite his senior career.

Jose Mourinho has given Walker-Peters the green light to secure a transfer after handing him just one appearance since he took over as manager.

In total, the defender has made 24 appearances for the Tottenham first team since emerging from the club’s youth ranks.

He started this season in the first XI, starting the first three Premier League matches at right-back under Mauricio Pochettino.

But Walker-Peters has subsequently made just two appearances, one in the League Cup and the other in a Champions League dead rubber against Bayern Munich after last-16 qualification had been sealed.

Former Spurs goalkeeper Paul Robinson told Football Insider earlier this season that Walker-Peters is an “outstanding young talent” who deserved to be given a regular run of matches in the team.

It is not an opinion that has been shared by Mourinho, who has instead put his faith in Serge Aurier on the right side of defence.

Aurier has started all 10 matches since the Portugese took over as manager.
