While the New York Giants and New England Patriots battle in Super Bowl XLVI might be the most entertaining football game on Sunday, the Premier League showdown between Manchester United and Chelsea could easily be the most-watched football match this weekend.
Both English powers have a lot at stake in this match. For the Blues, they are trying to hold on to their five-point lead over Arsenal in the league table for the fourth and final Champions League qualification spot.
Chelsea will also want to avenge their 3-1 defeat at Old Trafford in September when United embarrassed them for 90 minutes.
The Red Devils could take a lead in the Premiership with their second victory over Chelsea this season, and getting a positive result against the Blues would also be a tremendous confidence booster.
Let's look at everything you need to know about this amazing Premier League matchup you must watch on Sunday.
Player to watch for Manchester United: David De Gea

With the news that backup goalkeeper Anders Lindegaard will miss about four weeks with an injury, David De Gea will be forced to start against Chelsea, and this could be a problem for Manchester United.
De Gea has had major issues playing in the Premier League this season, his first in England, and in a huge pressure game against Chelsea, he could get rattled and hurt United's chances of winning.
He was terrible against Liverpool on Saturday in a 2-1 loss to the Reds that saw United exit the FA Cup. De Gea will certainly be someone to watch on Sunday.
Player to watch for Chelsea: Juan Mata

Juan Mata has been Chelsea's player of the season is the biggest playmaking threat that Manchester United has to defend.
Mata has good pace, he can score goals and he has exquisite passing skills. He will need to be at the focal point of the Blues attack on Sunday for his club to earn a positive result.
If Mata doesn't create quality scoring opportunities for himself and his teammates against United, then Chelsea will struggle to score goals.
Key Matchup: Chelsea Defense's Defense in the Defensive Third, Especially on Set Pieces
Chelsea fell down 1-0 early United when the two teams met earlier in the year at Old Trafford because they poorly defended a free kick and left Chris Smalling with a free header in the box.
Chelsea have to defend better in the defensive third of the pitch to have any chances of earning a positive result in this match. A win would be huge for their confidence going forward, but they won't win unless John Terry and the back four as a whole don't make costly mistakes.
Falling behind early again could doom Chelsea for a second time against United.
What They're Saying
Sir Alex Ferguson spoke to the media this week regarding the injuries of Lindegaard, Wayne Rooney and Nani.
"We're hopeful Wayne Rooney, Nani and possibly Ashley Young will be fit for Sunday," Ferguson told MUTV.
"Anders got injured in training and then David got injured at the end of training, so we had a right nightmare there," he noted. "Ben Amos didn't have a lot to do but he was confident and he was composed. I'm pleased with that."
Chelsea won't have Ramires for the United clash after the Brazilian suffered an injury this week.
Ramires, 24, picked up a medial knee ligament problem in the second half of the fourth-round tie when he tried to block a shot from Clint Hill. A Chelsea club statement said: "He is expected to be out for three to four weeks."
Prediction: Chelsea win 2-1

Chelsea will be the more desperate team on Sunday, and they have greater things at stake. Making the Champions League next season is something that the Blues have to accomplish, and losing this match will allow Arsenal to cut the gap between the clubs to two points.
With the pressure that De Gea will be under in this match, United could have a real problem at the goalkeeper position. If United lose this match, they will travel to host Liverpool next Saturday in another grueling battle that could be a must win for their title hopes.
Chelsea will give an inspired performance against Manchester United at home this weekend and earn a huge result for the club.
