Arthur is Costa 2.0 waiting to happen. Small Brazilian that gets you excited by his play style, speed, ball control, flair etc., but is hugely inconsistent, injury prone and leads a mostly unprofessional life.
He may be a hit, but a whole lot of ifs need to fall in place for that to happen. Thanks but no thanks. Aouar, VdB, Pogba ofc, even Pellegrini for me.
