He is really small, but I bet if we were to look back at 17 yr old Sadio Mane and 17 yr old Mo Salah, they would be rather small as well.
He is an exciting prospect with seemingly unlimited confidence and bravura. Once he gets some adult strength like those other two forwards, he could be special. Of course a lot can happen between now and then, but no doubt he looks a real asset for us.
