It was a banner day for Spaniards abroad in England, as both Michu and Cazorla enjoyed spectacular introductions to Premier League football.
Cazorla couldn't be more different from his compatriot when styles of play are considered, but the international stalwart was far and away the best player on the pristine Emirates pitch Saturday.
Not since Cesc Fabregas left for Barcelona had Arsenal fans witnessed such a mesmeric display in midfield. Cazorla was everywhere throughout the first half, shedding aside worries he might have brought heavy legs back from a midweek friendly with Spain in Puerto Rico.
Robin van Persie once said that part of Fabregas' brilliance and disproportional influence in games stemmed from his ability to play much quicker than his physical limitations would otherwise have allowed.
It was the Catalan's ability to think "two seconds ahead" that thoroughly impressed the Dutchman, who frequently had to deal with the neat combinations and deft feints employed by Fabregas in training.
Cazorla's a far cry from "lumbering," but like Fabregas, he is not blessed with searing pace.
You'd never have known it on Saturday, however, as Cazorla flummoxed Sunderland's defense so thoroughly in the opening minutes, using the tricks Fabregas had employed in training, that Black Cats manager Martin O'Neill had midfield enforcer Lee Cattermole man-mark him for the rest of the match.
It worked in stages, but Cazorla still found openings in the opposing defense, perhaps seen best in his neat little pass for Olivier Giroud, who despite finding himself open on goal fired well wide of the target.
