I'd take the chance on fati, he's still got crazy potential, his injuries are down to how bad Barca's medical and physio are.
I watched a video as I thought he was just injury prone but it explained how unlucky he's been and how incompetent Barca are , but it's because Barca rushed him to heal from a 6 month injury in 4 months. Making him do 3 recovery sessions a day when cugat said 1 recovery session a day completely ignoring the doctors advice.
Which meant his knee couldn't recover in time and just ended up getting reinjured needing more surgeries.
