Fosu-Mensah has more than 50 pro games and more than 40 in the Premier League, the guy is also 21, nobody says he will be a world beater nor good enough, but our options are horrendous, Fred sometimes doesn't even look like a pro footballer, and Matic is even worse. Nobody really knows his ceiling but stranger things have happened in football, if maybe he could find himself a role in the squad, he might still have a future. Unfortunately injuries have derailed his career, and there is very slim chance but if he is to stay here we should use him until the end of the season.
I meant very good for an 18 year old making his debut in a shit show that we were, it is an extreme answer I agree. My point is, we might as well use him while he is here and our options are as bad as they are.
