Barcelona midfielder Ivan Rakitic says they're aware there's more to Chelsea than Eden Hazard.

Barca are in London for the first-leg of their Champions League round 16 tie at Chelsea tonight.

Rakitic said about whether Hazard is world-class: "For me, he is.

"He's maybe the most important player for Chelsea. But we know that Chelsea are not only Hazard.

"For sure, we have to be ready tomorrow to stop him. We know he's really fast and goes one-against-one.

"In his last games, he's in really good form. We have to be ready for him.

"But also for the whole team. It will be a very special game tomorrow, and we have to enjoy it."
