The mood at the Manchester United training ground has been described as "depressing" at a time when Manchester City have given an insight into life behind the scenes.

City have recently released a documentary to give supporters an insight into how the club has been transformed both on and off the pitch, and that has allegedly had ramifications at United's training base Carrington.

According to The Sun, there is currently a "miserable atmosphere" at the North-West giants after their worst start to a Premier League campaign since 1992.

An insider is quoted as saying: "There is the usual miserable atmosphere running through the club. Nothing has changed. Some of us have just finished watching the City documentary and it shows how light years we are behind them.

"It's probably the same for many others now as well. It is thoroughly depressing at the moment."

United reportedly have no plans to make any significant changes at the club, with Jose Mourinho expected to remain in his role as manager.
