One less piece Valverde can use in his puzzle ahead of the Copa del Rey final. It will be the first time that the Camp Nou plays host after the painful Champions League elimination against Liverpool.
It is the second injury suffered by Arthur in his first season with Barcelona. The previous time was in February, when he was off the field for four weeks with a hamstring problems.
Valverde will have to wait to know if he can count on the Brazilian in the final of the Copa del Rey. According to the medical report done by Barcelona, his development will dictate his availability for future commitments.
He is not be the only big casualty for Barcelona in the Copa del Rey. Valverde already knows that Luis Suárez won't be fit, after having injured the internal meniscus of his right knee this week.
