Chelsea midfielder Frank Lampard has paid tribute to Eden Hazard following the Belgian's superb performance in the 4-3 win at Sunderland on Wednesday.
Hazard scored twice for the Blues as well as creating their opener for Lampard as Chelsea maintained the pressure on Arsenal at the top of the Premier League.
Lampard said: "Eden Hazard was different class. It's the best individual performance I have seen in a while.
"The only player who is probably putting in those sort of performances is Sergio Aguero.
"This season he has put in some individual performances which I have seen some of those from afar, but to play with, that was just top drawer.
"He kept slipping inside people and getting his shots away. He was the big difference. As a team, we played very well, but he was that little bit of extra quality that wins you these games."
Chelsea now face another tricky trip to Stoke on Saturday and Lampard knows they must remain fully focused for that game.
He said: "We have got the squad, we have got the players, we have to get ourselves up for every game, we have to really, really focus because every game is difficult these days.
"More than ever, that's true. Coming up to Sunderland, going up to Stoke on Saturday - if we go up there with the wrong attitude, we won't win, so it's up to us."
