FACT: In spite of all these problems you see him creating, you won the title this year after a long drought when you were clearly the 3rd best club in England. Since he took over you are arguably the best. Better domestically than Liverpool and probably the equal of Chelsea at home and abroad. You weren't sniffing the title before May 2005.
FACT: Since 2005 you have bought van der Saar, Vidic, Evra, Park, and Carrick. All extremely important to your title. He has not dismantled the club, like most of you shouted from rooftops that he would do, and he has not alienated fans. If anything this season has brought you all together.
He was absolutely vital to the success, and your turn around does not happen without him no matter what you want to claim. You are so mad that you haven't bought more players, but for what!? You won the league, outperformed all but two teams in the CL and still have a shot to win the FA Cup. Even with more depth, you could have screwed up the chemistry and failed. Honestly what more do you want?
Plus, your club is very clearly on the rise right now. You aren't going to go down, you're going to get better. The team is young and extremely solid. And by the way you did make an enormous bid for Owen Hargreaves that will likely be accepted this summer, which really destroys your argument that he isn't willing to splurge on transfers. Perhaps he is just willing to splurge on wise transfers and not on bench players?
He has done EVERYTHING right and nothing wrong. Unless you want to complain about arguably your second best season ever, I think you guys should just eat the crow and apologize to the man. He has done everything a good owner could do.
