lorddulaarsenal Admittedly hasn't been great after his injury and he's been through hell already, but he's only 20 years and if the price is decent I'd see it as a chance to get one of the biggest talents in the world. Before the injury he seemed destined for stardom at just 17 years. Creativity, finishing and dribbling already in his locker back then.
According to The Athletic Barcelona mismanaged him after the initial injury and gave him twice the workload recommended by his doctor, and then it got worse and snowballed from there. Tbf I know nothing about knee-injuries so for all I know maybe he won't be the same player even if he's young. Maybe if @speedy is still here.
