The final player for me that needs to step up this weekend is Tom Cleverley.
The England international has made central midfield his own at the Red Devils this year and has combined well with Michael Carrick, but he will face a huge test against Liverpool's midfield in this one.
Steven Gerrard, Joe Allen, Lucas Leiva—that is the trio that Cleverley will have to operate against and succeed in both attack and defense if United are going to win this football game.
Rooney's absence means a lot of the responsibility in winning the ball back will fall further down the pitch to the likes of Carrick and Cleverley, and they must rise to the occasion. If they allow Gerrard and Allen room to operate, Liverpool do have the proven talent to find the back of the net against their rivals, and United will struggle to win this football game if that happens.
However, it isn't just defense for Cleverley, who can contribute greatly to the Red Devils attack by chipping in to give that extra man advantage here.
He is excellent from long range and good at moving the ball across the top of the box, which could well create the opportunity that the likes of van Persie, Hernandez or Kagawa need to find the back of the net and win this game for the Red Devils.
If Cleverley can keep his head and succeed here, you'd have to think that the Red Devils will be very tough to beat at home this weekend.
Who do you think are the key players for Manchester United vs. Liverpool?
