It has been a disappointing season in the Premier League by Crystal Palace's usually high standards.

The Eagles have won only one of their last six games and fell to a 4-1 home defeat to Chelsea last time out.

Goals from Kai Havertz, Christian Pulisic and Kurt Zouma secured a big win for Thomas Tuchel's side at Selhurst Park.

Palace will now look to return to winning ways in under a fortnight as they prepare to take on Leicester City at the King Power.

Whoever takes the reins next season, whether that be Roy Hodgson or someone else, they will be keen to strengthen their squad.

There are a number of players on the books at Selhurst Park, with many out of contract in the summer and many likely to attract potential suitors.

Here, we take a look at eight players Palace could sell or release ahead of a busy summer transfer window, in order to make way for potential incomings...

Cahill has made 16 appearances in the Premier League this season.

His contract is up in the summer, though, and could be set to leave Selhurst Park.

Henderson is also very likely to leave.

The goalkeeper hasn't made a single first-team appearance since joining on a free transfer and is out of contract in the summer.

McCarthy has made only 12 Premier League appearances for the Eagles this season.

He could be on his way out with his deal up in the summer.

Sakho was linked with moves away earlier this season.

The defender has featured only four times in the league this term and could be set to leave on a free this summer.

van Aanholt has been strongly linked with a move to Turkey to Galatasaray, with the club reportedly offering a three-year pre-contract agreement.

There's every chance of him leaving this summer.

Wickham has been featuring for the Under-23s' in recent weeks.

It's likely that he will leave this summer on a free transfer.

You can never really be sure of Zaha's future at Palace.

He has nine goals in 23 league games this season and may attract interest this summer.

Kelly's future is undoubtedly up in the air.

He hasn't made a single appearance in the Premier League this term, and is out of contract in the summer.
