Crystal Palace will target Watford's Ismaila Sarr as a replacement for Wilfried Zaha should the Ivory Coast international depart for Chelsea.
Palace have drawn up contingency plans should Chelsea firm up their interest in 29-year-old Zaha who only has a year left on his contract at Selhurst Park - and Sarr is top of the wishlist.
The Watford winger has been subject of previous interest from Palace but they baulked at the £45million price tag.
However, the asking price will have dropped to a more realistic £25million following The Hornets relegation from the Premier League.
