Manchester City are looking at Ben Chilwell to replace Benjamin Mendy.
While manager Pep Guardiola has lauded Mendy's ability, the club are growing frustrated with his injury problems.
The Frenchman has made 15 appearances in two seasons at City.
City are also frustrated with Mendy's attitude towards recovery and other off-field incidents.
Goal reports the club's hierarchy have had enough and want to pursue a deal for 22-year-old Chilwell in the summer.
