At this point I really don't know what's the problem at Manchester United. They spend money in the transfer market every season, but they just can't seem to get it right.  I don't know if it's players, coaching staff or the board,  all I know is that Manchester United need to sort things out fast. The team was so bad against Grimsby and I can't fault Amorim for the lose, rather its the players that should be blamed. I don't think they even need a coach to play Grimsby.
I had so much much expectation from Manchester United after I watched them played Arsenal on the opening of the season, but I think that was just a joke.
