Sergi Roberto out for between three and four weeks LaLiga Santander - FC Barcelona Break in the semimembranosus of the left leg

In a blow for Barcelona, midfielder Sergi Roberto will most likely miss what is left of 2018, after his medical diagnosis ensured he would be out of action for between three and four weeks.

Against Atletico Madrid, Roberto suffered a muscle injury in the semimembranosus of his left thigh after a coming together with Koke.

He immediately signalled to the bench, and Rafinha came on in his place.

The best case scenario for the player will see him back for the game against Levante, but on the other hand, if the recovery is delayed, he won't return until 2019.

It is the second muscle injury he's had this season.

The first was at the end of September, in the match against Athletic Club, and caused him to miss four games.

It means that Ernesto Valverde has once again lost the most versatile footballer he has in his squad.
