Crystal Palace and Stoke want to sign Swansea defender Kyle Bartley, reports say.

The former Arsenal trainee has one year left on his Swans deal and is not in the first-team picture.

Bartley starred in a loan spell for Leeds last season, playing 50 times in a team that just missed out on the play-offs.

And The Sun reports that his impressive form has alerted Crystal Palace and Stoke, who are both in the market for central defenders.

Despite the impending £8m arrival of Ajax youngster Jairo Riedewald, Eagles boss Frank de Boer still wants to add to his backline.

James Tomkins and Damien Delaney are Palace’s only fit centre-backs with skipper Scott Dann still recovering from a knee injury.

And with Bartley behind Federico Fernandez, Alfie Mawson and Mike van der Hoorn in the pecking order at the Liberty Stadium, he could get a chance to feature more regularly under De Boer.
