The state of some posts, especially the OP.
If you think that he's a checkbook manager who just slotted in that Barca side and that any other one could get any of his teams play at the level we seen them do, then you should honestly give up on football. One can (rightly) point to the lack of European trophies at Bayern, Man City's case not being closed yet, but to call him a fraud is absolutely ridiculous. One of the greatest managers of all time SAF, won the CL just twice, Wenger never won it. Poch completely transformed that Spurs side, yet never won a title with them. Are they frauds too?
The money argument doesn't hold much water, especially in United's case who more or less spent the same amount of money with the results we know.
