Manchester United quality is better than both teams they'll face. I think they'll likely win matches over Grimsby, even if it's only by a narrow scores 1-0. In the EPL match, I think Burnley can take an advantages to get a point from United. A draw is still a reasonable result for Burnley. But if United fail to win these two matches, I think they should immediately make the decision to change their coach again, before too late.
Manchester United couldn't even beat Grimsby... When exactly are they going to start winning I wonder? One can say it's the beginning of the season etc. but man, come on!
You can't be that bad to be defeated by a 4th league club.

Now they are going to focus on the Burnley game in the PL in 3 days. It's at Old Trafford. I hope they finally break a leg.
