I think he is the best young player we have ever had under 21. Better than Saka, Anelka, even Cesc who was captain at 21. When he is switched on he dribbles past players like they don't matter. He completely did TTA and even Cancelo, but in those games against Liverpool and City he didn't produce an assist or goal despite almost scoring in both games. Thats his next step, to fine tune the final product whether it be his finishing or the final pass. Its not like he is bad at both, he is good, but given he can put himself in those positions by going past players so easy, if he fine tunes this aspect of his game then he can go to the next level.
Had a decent debut for Brazil on the weekend, looks a high chance to make the squad & I back him to elevate himself above Vinicius Jr and be Brazils main man in the post Neymar era.
Saka on the right, Martinelli on the left, so often we stretch teams and pull them apart due to both players needing to be double marked. If we can a worthwhile striker to take advantage of all the issues Saka and Martinelli cause Arsenal go to the next level. Its so frustrating with Lacazette.
