I don't think all the issues united have can be laid at his feet.
Personally, I would have taken the next job and run as far as I can from united. The glaziers are terrible owners and they have somehow managed to bring an investor who is worse. Ok, he's better at the propaganda side of running a club. Some of the stuff you hear about him. As an example, charging staff £20 for travel to wembley for the cup final. Making people redundant to cut costs, whilst still paying players astronomical prices for players and this whole "we want a wembley of north............please British tax payer" no lad, you are a billionaire, who has invested in one of the biggest clubs on planet. Worth billions itself you f*****g pay for it. (Learnt my lesson admin) Or at least, actually fix the stadium in the first place, so it doesn't become Britain's fourth largest waterfall whenever it rains. Which in Manchester, it does tend to.
Ten Hag maybe stopping, any united should still worried at the poor state the club is run. The first thing ten hag should do, is puff his chest. Walk into the board and say "I need new players, I need the Deadwood clearing and for god sake Sir Alex, please go. Your not helping me by being in the stands"
