"Exactly"?
Ronaldo comes to mind, the player who refused to take the pitch when called on by his manager (v Spurs, in case you're not aware of this) and then went to Piers Morgan to trash the club, but let's stipulate for the sake of fantasy that every PL manager has a whingey Ronaldo to deal with. Let's not forget Jadon Sancho, who has behaved like a child yet, incredibly, performed on the pitch like a 37 year old. The Greenwood matter in no way can be blamed on ten Hag. And now Marcus Rashford, who flies to Belfast the night before a training session so that he get hammered with his mates.
It's not as though the British media have refused to report on any of this so it's a bit staggering that you really had to be informed of "exactly" what is already widely known.
Yes, it could well be that ten Hag is a shit manager, but no one can deny that he's had to deal with shit that no other PL ever has before him and I can't think of another manager in any other sport has ever had to deal with. Not even Billy Martin of the New York Yankees in the 1970s had to deal with anything like the freak show of spoiled brats that ten Hag has had to deal with. And if you actually read my previous posts on ten Hag you'll see that I'm only suggesting that we let him see the season out and then assess our options. There is no manager waiting in the wings we could bring on right now to right ship. There is no realistic hope now of CL qualification and all that's left is either qualifying for the Europa or Conference League and of course the FA Cup.
