FC Barcelona have designed a plan along with Samuel Umtiti for the French defender to reduce the problems in his knees.
Per the show 'Qué t'hi jugues?' on Cadena Ser, the French defender has lost weight so his knees come under less pressure.
Umtiti has been treading lightly for a month and a half, taking treatment for the cartilage in his left knee, which flared up against Athletic in La Liga.
Since then he has missed nine games, five in La Liga (Athletic, Valencia, Sevilla, Real Madrid and Rayo Vallecano), three in the Champions League (Tottenham and both Inter games) and one in the Copa del Rey (Cultural Leonesa).
During the treatment period there were moments of doubt in which surgery was an option, which would have kept him out for four months.
Although he didn't play, Umtiti was in the squad for the Real Betis game. Now they believe his weightloss will stop him suffering more problems.
