After suffering an injury in the patellar tendon, Fati saw less and less minutes when the starting attackers were recovering. The young Barcelona starlet hasn't played for them since 24th September.
That day he played 12 minutes against Villarreal, coming on in the 2nd half. The 4 matches after that he didn't feature and the fans are now missing one of their most exciting academy graduates in the last few years.
Ansu Fati played due to the absences of Suárez, Messi, and Dembélé, so when they returned, he became the backup option. However, Dembélé's suspension will help him.
The attacker is expected to be on the bench against Valladolid and come on in the 2nd half since Barca are facing a spell where they will play lots of matches, and it would be strange if Valverde didn't rest any of his starting attackers at some point.
