Either Allegri or Wenger as caretaker manager. Personally, I think Allegri has got his heart set on succeeding Pochettino at Spurs and apparently he doesn't want to move until the summer.
Nah, the time has gone. As PaddockLad said, we did have a few injuries (Shaw, Lindelof, Wan-Bissaka, Pogba, Martial from our starting XI, Lingard, Jones and Bailly from the squad) but that is no excuse when before the season even started it was clear that we needed at least another midfielder and a couple more attacking players. Instead, Herrera went along with Lukaku and Sanchez and all we did was bring in James who should have been eased in as a squad player but instead he's been thrust into the starting lineup. Was clear before the season started that we'd do poorly.
When Ole first came in, we did well then it fell apart. Was stupid to appoint him as permanent manager when we did - the only reason I can think is Molde's season was about to start and their owner wanted to know Ole's future so they could plan their season. The final few months of our season after he was announced as permanent manager were dire.
Only nice thing I can say is that compared to Van Gaal and Mourinho who were obsessed with starting Rooney and Matic respectively when they were clearly past it, he has changed players in the lineup when they're not working. Examples being putting Martial up top instead of Rashford, Tuanzebe playing over Lindelof, dropping Lingard from the starting lineup... basically the minimum you'd expect from any manager but Van Gaal and Mourinho really were stubborn with who they played. Downside with him being everything else.
