Its interesting watching that Neville clip, 2nd vid, where he talks about the dressing room. When Ole took over there were a lot fewer big names in the dressing room. The only real difficult situation was Pogba, and Ole just made him the main man, problem solved. Combined with his reputation and support from the Stretford End it was pretty clear Ole was the boss, whatever his CV.
Things are different now though. Bruno is a huge fan favourite and is basically undroppable. Rashford is becoming bigger than just a footballer these days. Ronaldo and Varane have come in with seriously heavyweight CVs and want to win. With Pogba, he can't just give him anything he wants. The dynamic is different. It feels like the dressing room has gotten volatile. Combined with the fact that its crunch time - arguments about a rebuild increasingly sound like jam tomorrow - and I don't think Ole can rely on the players to continue to back him if they don't fully believe in him.
