Manchester City defender Benjamin Mendy on Wednesday underwent surgery on his injured left knee and faces another spell on the sidelines.
It was learned that the problem was a meniscus injury, rather than a more serious anterior cruciate ligament (ACL) injury, but it is understood Mendy will be unavailable to play for City again in 2018.
The Frenchman, who joined City from Monaco in a £49m deal last year, missed 43 games for the club after suffering an ACL injury in his right knee, just two months after his switch to Manchester.
Mendy played the full 90 minutes in City’s 3-1 derby win against United last weekend and reported for international duty with France on Monday.
But he withdrew from France’s squad on Monday afternoon before travelling to Barcelona where scans revealed that surgery was required.
The 24-year-old’s surgery was performed by renowned knee surgeon Dr Ramon Cugat, who also treated the full-back after he sustained an ACL injury against Crystal Palace in 2017.
