Manchester United are reportedly frustrated with the fitness situation of Edinson Cavani.
The Uruguayan joined on a free transfer last summer and he has since registered seven goals and two assists from 25 appearances.
Of late, he has been on the sidelines with a calf problem and M.E.N claims that this has led to frustration among the club’s staff.
Cavani returned after a 17-day gap to face Crystal Palace, but he has been unavailable since with a fresh muscle injury.
It is unclear whether he will make his comeback for the second leg of the Europa League round of 16 tie against AC Milan.
The Red Devils drew 1-1 in the home leg against the Rossoneri and they must score at San Siro to stay in the competition.
