A game that never really hit the heights you would expect from these two outstanding sides, but was ultimately settled by two moments of sheer class.

We're under way and Sir Alex Ferguson has confirmed Rooney has a groin injury picked up on England duty last week so that clears that up! I can also report that managers Benitez and Ferguson DID shake hands before the game.
"A fascinating game which could go either way, especially with Ferguson, once again, deciding to leave Rooney out (something is not right there no matter what they say). Man U are just about home and hosed with the title but Chelsea need to give their fans something to cheer about so perhaps the pressure is all on them. I'm going for a 2-1 United win with Hernandez and Van Persie (winner from the bench)," says Pete Shields - a Newcastle fan.
Baz Brennan says: "Shocked that Rooney has been left out, omens not looking good for wazza, days might be numbered. Still fancy United to get the job done. I'm saying 2-0 United."
Our colleagues at Sky Bet make Chelsea 6/5 favourites to win the tie in 90 minutes, with United 2/1 and the draw 13/5. Chelsea to qualify is 4/6 with United 11/10. The hosts to go through in extra time is 17/2 with United 11/1.
"With RVP's barren run, I'm glad to see Chicha playing. United to come from behind to win 2-1 with RVP and a late Hernandez winner cancelling out a Mata goal," predicts Morgan Roberts.
Benn Phillips says: "Both teams have looked good recently. I think we could see a penalty shootout."
Full team line ups are - Chelsea: Cech, Azpilicueta, Ivanovic, Luiz, Cole, Ramires, Mikel, Hazard, Oscar, Mata, Ba. Subs: Turnbull, Lampard, Torres, Moses, Terry, Benayoun, Bertrand.

Rio Ferdinand returns but Wayne Rooney is again absent as Manchester United take on FA Cup holders Chelsea in today's quarter-final replay at Stamford Bridge. With a Wembley semi-final against Manchester City on April 14 the prize for the victors, runaway Barclays Premier League leaders United make seven changes from the side which won at Sunderland on Saturday, with Robin van Persie on the bench and Rooney not in the matchday squad. Chelsea, seeking a fifth FA Cup in seven seasons, also make seven changes from the XI which began the loss at Southampton, with John Terry and Frank Lampard on the bench and Demba Ba starting up front.
Scotty in New Zealand cannot believe Fergie leaving out Rooney again ... but says: "Mind you Hernandez scores all the time against Chelsea!"
"I see no problem with 2 games in 48 hours, non league clubs have to do it and without the facilities, staff, squads etc of prem clubs. Team news today can only mean a Chelsea win for me," says Ryan Storrie in Brighton.
First e-mail from Michael Dingle who says: "We need Hazard, Mata and Oscar starting today and starting well. Going for a 2-1 Chelsea win with either Mata, Hazard or Oscar with one and Lampard getting a goal."
The Chelsea team is Cech, Azpilicueta, Ivanovic, Luiz, Cole, Ramires, Mikel, Hazard, Mata, Oscar, Ba with Terry, Lampard and Torres on the bench. United line up with De Gea, Jones, Smalling, Ferdinand, Evra, Valencia, Cleverley, Carrick, Nani, Welbeck, Hernandez and the big news is that Wayne Rooney does not make the bench although it seems he has a groin injury picked up on England duty.
Good morning (just!) and welcome to our coverage of today's FA Cup quarter-final replay between Chelsea and champions-elect Manchester United at Stamford Bridge. The Blues fought back from 2-0 down at Old Trafford to force this replay, but due to fixture congestion it means this was the only available date so both sides will be playing for the second time in 48 hours. I don't have a problem with that as it always used to happen in years gone by, but what do you think? Send your views to firstname.lastname@example.org and I'll publish the best ones.
