Chelsea assistant manager Ray Wilkins rates this weekend's clash with Liverpool as a looming classic.

Wilkins expects the game to be "humdinger" and did not blame Manchester United's Wayne Rooney for asking the Reds to "do United a favour and beat Chelsea".

"It's a massive, massive game for us on Sunday and Rooney is quite right, he would want Liverpool to do Manchester United a real favour," said Wilkins.

"Liverpool will put themselves out and they have to do that as professional people, we expect no favours from them whatsoever. The game on Sunday will be and should be a humdinger.

"Even if Liverpool were to beat us and offer the championship to Manchester United, that's what they have to do, that's their job, that's their work. They have to try 100% to do that," Wilkins told talkSport.
