Modric will not want to see that again in a hurry.

This is the second time in the space of two weeks that Alba has mercilessly embarrassed an opponent with a nutmeg.

Against Deportivo in the 4-0 win, both he and Messi took part in a form of footballing torture, nutmegging Carlos Gil twice in the space of five seconds.

Modric only suffered the once, but that is surely more than enough.
