Manchester United will definitely going to be having a long ride in the coming weeks regarding their fixtures, lol. They will face an inform Nottingham Forest and after face one of their fierce rivals Manchester City although City is currently dip in form, maybe they might breath a little.
The third opponent is Newcastle United, I believe they are stronger than Manchester United even though their performance is also shaky. I doubt if Manchester United can get up to 5 points in this fixtures.
Man U, won't come out strong after the three matches. These are tough moments that appear as though designed to push back the red devils ranking on the table. A win on Nottingham forest would mean a lot to the Amorim side, and it'll pose a threat on all other coming opponents. On the opposite, losing to forest will bring down Man U's tempo to face City, and so, Amorim won't be in an excellent condition to take all 3 points from Pep.
