Aston Villa wing-back Ahmed Elmohamady has admitted two Chelsea greats have been his toughest opponents.
The Egypt international recently celebrated 10 years in England.
He told Sky Sports: "The best is Eden Hazard. He was one of the toughest and he is so talented. He is one of the best in the world, really world-class, and going up against him was really tough because you didn't know what he was going to do, and even when he did it was difficult to stop.
"And in terms of going up against a defender, Ashley Cole was the best. He was so difficult to get past and he'd be constantly on you, and he could attack too and get in behind."
