The 30-year-old had been in excellent form for Man United since the start of 2016 but now faces an extended period out with an injury.
This injury means he will definitely miss our game against Arsenal at the end of February and is likely to also miss the Manchester derby in March, plus other crucial games in between.
It’s a cruel blow to United’s fading hopes of a top four finish and only makes the job facing Louis van Gaal that much harder.
Without Rooney, Anthony Martial will likely move back up front or Will Keane will get a big opportunity to replace Wayne as our main striker to leave Martial out on the wing where he has been so devastating in recent games.
We’ve had atrocious luck with injuries this season but van Gaal only has himself to blame in this particular situation as we failed to adequately replace the outgoing Robin van Persie, Radamel Falcao and Javier Hernandez which has left us with very few options in attack.
