Harry = manager
AVB = Head coach
Its clear that Levy is BACKING his manager/coach/team this time. The money has been made available, he's pulled in one of the best DoFs (by all accounts) going to help him. AVB wanted a DoF.
The team under Harry was fantastic, but i always got the impression Levy did not trust him fully. The england job fiasco sort of prooved him right. It seemed that he never really took the leash off the transfer spending when Harry was calling the shots, hence the signings like Saha even though we got in the CL!
Again, this is just my feeling, but i think Levy got Harry in to get us out a huge hole. Harry had experience in that area. I wonder whether Levy underestimated how well Harry would do and once he had he could not just get rid of him. With the first hint of a reason Harry was gone. This was ruthless even for "Sack a manager yearly Hotspur".
Despite the Bale bullshit there is a feeling (for me at least) of a change at the club. Last summer we did not have a DoF, and AVB doesn't do much with regards to transfers. There is also a possibility AVB was on some sort of probation. Now however you get the feeling that Levy got his man with AVB and he also got his man with Baldini, and hence he is backing them with the money that has undoubtebly been backing up over the last few years.
Thats how i see it anyway, anyone that disagrees can just dig a hole and die in it
