t’s the big one. Nothing more to be said. Even Man United's head chef has made it clear to Louis van Gaal the importance of Sunday's clash. It's England's "El Clasico" and the biggest for years.
With nine games to go, the "rat-race" for the top four is hotter than ever. Just two points separate fourth-places United from fifth-placed Liverpool. And with three points for Arsenal and Manchester City it adds even more importance to the tie.
United produced arguably there best display of the season beating Spurs 3-0. The result also makes it a third successive league match without conceding for the Red Devils.
United played with pace and intent that fans just hadn't seen for a long time. Wayne Rooney flourished upfront , Michael Carrick proved just how important he is to the side with a dominant performance in midfield and Marouane Fellaini, a man who's had his critics from Day One at Old Trafford, produced his best performance in a Red Shirt.
However no one in the league, not even Jose Mourinho's Chelsea, have come near Liverpool since the turn of the year in terms of form.
They are unbeaten since they were embarrassed at Old Trafford with a 3-0 defeat back in December . They also claimed a fifth successive victory with a bizarre goal from Henderson against Swansea City on Monday night.
Both goalkeepers , David De Gea and Simon Mignolet are in unbelievable form, the later seeing a huge transformation since being dropped by Brendan Rodgers.
The two talking points (one for each team) is - Does Di Maria start for United and Gerrard for Liverpool? Personally, no to the first yes to the second.
Di Maria needs a break. The red-card against Arsenal in the FA Cup was the cherry on a very ugly and vile-tasting cake that epitomizes his form at United since late October.
The off-the-pitch incident at home cannot have helped but his confidence is totally gone. His replacment Juan Mata was excellent last Sunday, in terms of pass completion and attacks in the final third. He should be rewarded with a place in the starting eleven at Anfield.
Di Maria could be the perfect impact sub if Van Gaal needs him, but the Argentine winger just needs time out of the spotlight and come back stronger.
As for Steven Gerrard, there's no way he won't start surely? His last ever game against United , at Anfield. He's been left out the team in recent weeks and used sparingly, almost like how Ferguson would use Giggs and Scholes and save them for the games that he needed them in . And I think that's in Brendan Rodgers mind.
It's a game Liverpool need to win more than Manchester United. Granted if United win they go five points clear but in terms of form Liverpool are the favoruites by a country mile. It could be a total reversal of the previous encounter.
Oh, and the real "El Clasico" follows at 8pm. It's going to be a Super Sunday.
