Goals to Robin van Persie and Nemanja Vidic were enough to give the Red Devils all three points against the Merseyside club and continue their dominance on top of the Premier League ladder—giving them plenty of reasons to be celebrating at the moment.
Yet the win was soured by the fact that key players Nemanja Vidic and Ashley Young both appeared to suffer injuries during the match.
Both players have already missed several games this year due to injury and would be huge blows, respectively, if unavailable for United in the near future.
Vidic and Young were substituted off during the match against Liverpool, though no information is yet known as to what the injuries exactly are and what their severity is as well as subsequent impact on Manchester United's starting lineup.
Although United were unable to confirm the nature of the injuries sustained against Liverpool, each is thought to be a knee problem.
Vidic is only four games into a return from a second serious knee injury suffered during the past 13 months and he admitted recently that United's medical department is carefully choosing which games he plays during the first months of his comeback.
The captain appeared to have a problem after an aerial challenge on 65 minutes in which he also clashed heads but played on until he was replaced by Chris Smalling 10 minutes from the end.
Young was substituted at half-time following his heavy tackle on Daniel Agger just past the half-hour that caused his injury.
The impact of either player being out could have huge significance for the Red Devils, who take on West Ham in the FA Cup this Wednesday.
For Young, United would be left with Nani and Anderson as their only real options out wide on the left flank given that Danny Welbeck played the full 90 minutes against Liverpool on the weekend.
Both midfielders have only just returned to training and have missed the last eight games together due to their respective injuries (per The Guardian).
Wayne Rooney is also only just returning from injury—just to make sure that there is extra pressure on the Red Devils' midfield moving forward.
For Vidic, United's biggest concern will be filling the central defenders role given that Jonny Evans also suffering an injury at the moment. According to ESPN, the defender missed Sunday's game due to a hamstring injury and is nowhere near a definite starter for United's next football match.
That would most likely mean Chris Smalling takes his place in central defence for United, with Phil Jones another option if needed.
Yet with a must-win game in the FA Cup against West Ham looming Wednesday and then a huge clash at White Hart Lane against Tottenham Hotspur coming this weekend, now is not the time for United to be suffering injuries to key players.
They only just drew with the Hammers last time around in the Cup and have already lost to Spurs in the league this season—proving that neither result will be an easy time for Sir Alex Ferguson's men.
Hopefully, neither injury turns out to be a big deal for United and they are adequately covered by the players available in the mean time.
For it only takes one injury to completely derail a title campaign—something that the Red Devils are all too familiar with after last season's loss of Vidic and something that they will be desperate to avoid taking place once more in 2013.
Who would be a bigger loss for United—Vidic or Young?
