Barcelona face being without Sergi Roberto for a month.

Marca says 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.
