Manchester United is the biggest and most successful football side in English football history, winning major trophies including 20 league titles and 12 FA Cups

With this list of honours, Man Utd are expected to challenge for the Premier League title each year, especially this season with importance on providing the fans with more silverware, with their last top flight trophy coming in 2013.

The start of the season for Jose Mourinho's men left all Manchester fans feeling motivated, devoted and excited for the rest of the season but now they are 8 points behind their rivals, Man City!

So what is going wrong for the red half of Manchester?

Mourinho

Mourinho has a wealth of experience at some of the best clubs in Europe, including Real Madrid, Chelsea and Inter Milan, winning multiple trophies, like the champions league in the process. After winning the Europa league and the League Cup in last year, there was a general consensus that the former Chelsea boss would guide his side to more success in competitions that they used to dominate.

Manchester United are still the biggest club in England and are still able to attract the best players from around the world, proven when they signed Zlatan Ibrahimovic in 2016, despite no Champions league football. While the current squad are good enough to win the league title, they need to improve their approach to each match in terms of tactics rather than parking the bus against every top six side.

Injuries to blame

Injuries have been a huge let down for Man Utd so far this season with Paul Pogba, Ibrahimovic, Michael Carrick and Marcos Rojo all on the sidelines with expected return dates ranging from later this month to the end of January. Squad depth is a huge concern and there are not many options on the bench to affect the game.

The quality is there but the addition of more world class players would increase their chances of winning the Premier League. The financial backing of the board and Ed Woodward working behind the scenes along with their excellent scouting system, they have no reason not to invest in the winter transfer window to improve on the current team.

Man Utd are all-but guaranteed to progress to the knockout stages in the Champions league, but as the fixtures become more frequent, as we head towards December and the Christmas period, will they be able to keep up and mount a challenge to their rivals? Or will they falter and continue their league title drought?
