Chelsea ace Eden Hazard feels derby victory over West Ham United is vital.

The international break which follows Sunday's derby with the Hammers offers a pause for breath but first the Blues will seek to enhance their place in the top four as they bid to secure Champions League qualification.

"Three points are a must for us on Sunday - we need to win the match," Hazard, who scored in the Old Trafford fightback, said on Chelsea's official website.

"Chelsea are a big club - we have to win titles and to qualify for the Champions League. There's a lot to do but we'll try to do it all."
