i haven't watch him but only 1 game against inter in CL he outplayed them but other than that i don't know we need someone better than Willian to put competition for Saka and Pepe tho.
He's a left or right winger? TBH I know little about him and would want him to do well if he joined, but just seems underwhelming as we've been linked to him for some time now and no other clubs have come in for him.
