'Poor kid, it's taking him a long time': Koeman on Ansu Fati's recovery
During the presser ahead of the Atletico Madrid match, Ronald Koeman was asked to comment on Ansu Fati's recovery.
"Poor kid, it's taking him a long time... Yes, there were things that didn't go well but I don't want to go into it," the coach said, as quoted by Diario Sport.
"Five or six months is a long time. The most important thing now is that he is going to recover, that he's going to get well and that he will be with us. Too bad that it will only happen next season. His absence was a big loss for us."
Barcelona have confirmed that Fati has undergone a third surgery on his knee. He's expected to recover in two months, meaning that he'll be available for the pre-season.
The 18-year-old suffered a meniscus injury back in November. Initially, he was expected to be out for four months but the recovery didn't go as planned.
