Chelsea boss Guus Hiddink is determined to wreck Manchester United's Quintuple dream.
Hiddink said: "United like to have the Quintuple - it's even difficult to pronounce.
"They are in all competitions and it has to be respected how well they're doing.
"If you see how they played against Fulham, that's good to see as a passionate man of football.
"But we'd like to put some obstacles in front of their aim.
"If we threw the towel in, there'd be no competition. They're aiming at five, and that's a hell of a lot."
