Crystal Palace complete signing of Patrick van Aanholt from Sunderland

Crystal Palace have signed left-back Patrick van Aanholt on a four-and-a-half-year contract from Sunderland.

Sunderland confirmed last week that they had accepted a bid from Palace for Van Aanholt after he handed in a transfer request, with sources telling ESPN FC that the Eagles were paying a fee in the region of £12 million for the Dutchman.

Palace announced on Monday morning that a deal to sign Van Aanholt has now been completed, meaning the defender will link up with Eagles manager Sam Allardyce, who he worked with at Sunderland last season.

"I am delighted that Patrick has joined us. We had great success together at Sunderland where he was instrumental in keeping them in the Premier League last season," Allardyce told Palace's official website.

"He will add pace and energy to our team, has strong defensive qualities and has the added ability to score and create goals."

Van Aanholt spent two-and-a-half years at Sunderland, having joined the Black Cats from Chelsea in 2014.

Sunderland chief executive Martin Bain revealed last week that Van Aanholt had handed in a transfer request, saying: "If a player openly states he does not want to play for our club, then it is clear that we have a decision to make. In this instance and in regard to this particular player, we have done what we feel is right for Sunderland, which will always be our priority."

Palace are weighing up a move for former Juventus defender Martin Caceres, sources have told ESPN FC, while they are also looking into signing free agent Chris Samba and Olympiakos midfielder Luka Milivojevic.
