Manchester United's disappointing display in their 1-0 defeat against Wolves has not been well received by the club's fans. Many members of the Red Devils faithful have taken to Twitter to slam Ralf Rangnick's tactics during the game.Despite the likes of Harry Maguire and Paul Pogba missing the game through injury, Manchester United fielded a pretty strong team. The only shock decision in the line-up was Phil Jones partnering Rafael Varane in defense.Rangnick also opted to stick with the strike partnership of Cristiano Ronaldo and Edinson Cavani upfront. Mason Greenwood and Jadon Sancho occupied the wide positions in the German's preferred 4-2-2-2 formation. The midfield was anchored by Scott McTominay and Nemanja Matic in what was essentially the same side that demolished Burnley 3-1 last time out.Many would have expected Manchester United to win this game comfortably, but that was simply not the case. The Red Devils put in a terrible performance and were lucky to lose by only a 1-0 margin, courtesy of Joao Moutinho's strike in the 82nd minute.Their performance was comparable to the one they produced in the dismal 1-1 draw against Newcastle last week.Manchester United fans already seem to be dreading the second half of the season given the performances they've seen under Rangnick so far. Many took to Twitter to slam the German for his tactics, blaming him for the 1-0 loss against Wolves.

United host Aston Villa in the FA Cup next Tuesday, before traveling to Birmingham to take on Steven Gerrard's side in the league. One fact to note is that Aston Villa have already beaten United once this season in the league.The Red Devils will then end the month of January by hosting West Ham in what will be a crucial fixture in the race for the top 4.David Moyes' side are currently three points ahead of Manchester United in fifth, having played one game more than the Red Devils. Rangnick's side cannot afford any more slip-ups if they are to remain in the top 4 race come the closing stages of the season.However, if they continue to put in performances similar to the one they put in against Wolves, they might even struggle to qualify for European football altogether next season.
