Agreed, its a tough spot, as you said below he is talented. But I don't think he is a fit in the EPL. It might be time to say good bye, again. Get the money for him and use it on a CB and DM and Sancho. Yes I still want that right sided attacker and improvements in the center.
No, you can't have Pogba, Bruno, and VdB starting together for several reasons. None play holding or defense and there is no depth on the bench. The diamond with Fred or Matic holding could work, but I am not a fan of the diamond or all three together.
Losing to the Turkish team was much worse then you want to believe. Had they beat them both games United are already through. But they don't do things the easy way. I read that all they need is 1 point from the next 2 to advance. PSG at home this week and Lepzig away next. Their away form has been good, but they need to go take care of business this week so they aren't leaving it late. PSG is not in form but will want retribution. Neither game will be easy, they need to get up for it. And with a suddenly tough (and 5th place) West Ham in between, they need to keep the levels up.
If United wins their game in hand, they are level with Chelsea and in 4th on gd, 2 points behind Spurs and Liverpool. Is that good enough for United? No. But with no one running away with the league, it puts them in the mix.
