Crystal Palace defender Aaron Wan-Bissaka has reportedly emerged as a transfer target for Manchester United and Chelsea.

Wan-Bissaka has established himself as one of the top prospects in English football, with the full-back having already made 28 starts for the Eagles in the Premier League.

However, the form of the 21-year-old has led to interest in his signature and according to The Mirror, United and Chelsea are ready to fight Manchester City for the youngster.

United are looking for a long-term replacement for Antonio Valencia, although Diogo Dalot has already been earmarked as the Ecuadorian's successor.

Chelsea are allegedly happy to part ways with Davide Zappacosta, while the Blues will also be required to sign more homegrown players over the next two transfer windows.

Wan-Bissaka still has three-and-a-half years remaining on his contract at Selhurst Park.
