Spot on mate. The money has been there and they have been backed like you say. If they were winning shit you wouldn't hear a pip squeak, just like it calmed down a bit with Jose there.
There is always a blame game at that club, it's never ending.
I don't have much sympathy to be honest. At school/work/pubs we had these southern United fans who were obnoxious. They thought because they supported a club that won medals their opinion was superior and anyone else was irrelevant. Shitty comments about why do you support this club if they win nothing, what's the point etc.
Now they're in that situation and desperate to be relevant, Neville, Scholes, Butt, Keane all gazing into each other's eyes telling anecdotes of times gone by, desperate for it to come flooding back.
Ten Hag couldn't keep his trap shut, just like him with Ronaldo, who in turn spoke out. Now Sancho is speaking out. Instead of holding your hands up on the defeat you point to a prick who isn't playing.
