I don't know man.. It certainly is difficult to see Manchester united finishing amongst the top 4 spot this season. Don't get me wrong. I'm optimistic on their performance this season especially as they've bolstered their squad with new great signings. We just need to see actual improvements in the form of wins and number of goals scored.
I also think Mbeumo is an amazing talent and his impact would be really felt during matches. Kudos to Amorin for bringing him into the club. Their gameplay seem to have improved from last season, we just need to see more goals and wins. They really need to do much better if they actually want to make it to the top 4 spot.
You are right, Manchester United with the nonsense they are playing has no business with the top 4 position, even an Europa League spot will still be difficult for them to achieve judging from what they are currently playing now. Frankly, Manchester United made good signings but I feel that isn't enough as the backline was almost totally neglected during the window. The like of Liverpool, Chelsea and Arsenal has already gotten the top 3 positions, it's left for City, Tottenham and the rest to fight for the remaining spot which I don't see Manchester United in it.
