Number 1 Attribute especially which the fans want to see of a "Top Tier" Winger is decent dribbling. Fans gets excited by that and its a really important aspect to have the ability to take down whole defenses and create havoc. If you end up as a system Player whos more focused on passing you wont reach the heights of the best wingers troughout football history. Cause the greatest Wingers in History which we remember were mostly decent dribblers
He can decently dribble. It's common knowledge he get double teamed every time he gets the ball now, because he's that good at his job. 1 man can't take him.
Entertainment ≠ being a good winger. Adam Toure is is a great runner, one of the fastest but he has no end product.
Saka has impeccable desicion making, and multiple ways to attack. His link up play is great, as is his hold up, his vison and passing. He's also doing his best Robben impression with some of the goals he's been scoring. In fact, this season he's been involved in every Arsenal goal so far.
Can always grow more but he's easily world class. Being flashy ≠ being effective
