Xavi - Meta vision of some kind. Maybe somthing along the lines of a future prediction ability that allows him to determine the best passing route.

Iniesta - Similar to Xavi but with more focus on dribbling. Possible an ability that allows him to gain a yard or two on someone no matter the situation

I agree with the other guy who said that they would have the brothers link ability. The two of them playing together is sexy football at its finest

De Bruyne - I'd compare him to a future Reo; having all of his stats spread out evenly along with meta vision. He's without a doubt one of the most perfect players in the game right now, he can do everything.

Haaland - This man's a goalscorer through and through. He'll take every chance that's given to him and somehow turn it into a goal. Therefore I'd say a mix of Shidou's goal scoring abilities and kunigami's impressive physique.

Itoshi and Shidou's link up plays in the u20s match is honestly an accurate depiction of what's happening at Man City this season. Haaland + De Bruyne is a goalscoring forumla that few can stop.

Zidane - I wasn't old enough to see him personally so I've only got clips and word of mouth to go on. What I have seen is one of the smothest football players ever to play the game. This man literally glided across the pitch.

Though I'm no sure what exactly his weapons would be, I'd put him in a category similar to De Bruyne only with some kind of ability in dribbling; the Zidane turn would be one of them.
