Crystal Palace are close to a deal with Sunderland to sign Patrick van Aanholt in a deal that could rise to £12 million.

Van Aanholt, a £1.5 million signing from Chelsea in the summer of 2014, has been a regular in the Sunderland side since he joined but has not convinced the current manager, David Moyes, of his defensive prowess. 

Palace have been without a natural, senior left-back since Pape Souaré broke his thigh bone and jaw in a car crash on the M3 back in September.
