How much money did he spend? Baldini was the man brought in to sign the players.
Despite a lot of people raving about Spurs signings in the summer, I thought it was clear that they were short in terms of creativity. The time it's taking Lamela to adapt (if he does) has compounded that.
It's always hard to know where to apportion blame in a DoF type set-up but AvB can't be held completely responsible. He's got a £26m striker that relies on service and the players he's got serving him are Lennon, Townsend and Chadli.
I think it's a very rare club that brings in a DOF and both would ignore a manager who says "I don't want that player" or ignores the suggestions of the manager.
Most clubs would have a DoF , just in a different name. Dein was probably everything a DoF was for Wenger, Wenger tells him who he wants, Dein goes and does it. It probably helps managers who want that help, DoF gets to deal with new contracts so if the Dof doesn't give the player as much as he wants or plays hardball, it somewhat insulates the relationship from the manager.
For all we know AVB chose every single last player, unless I hear otherwise I will assume that is the case, because few clubs(outside of Chelsea/Real) go around buying players and forcing them on a manager, the entire staff is there to bring about the vision of the manager.
AFAIK, AVB chose Soldado, knowing what type of formation and team he wanted to play, that choice was incorrect. He chose Holtby and despite being **** every single game, continues to play him because he thinks he's great. Lamela is taking time to adapt mostly because AVB won't play him, Defoe has no form because AVB is refusing to play him consistently. They have no left back because he forced BAE out of the club for no apparent reason.
AVB is responsible for the majority of what is going on there, it was AVB by all accounts who pushed Ade out of training, did the DoF ask him to do that. Did a DoF ask him to pick a couple players at Chelsea to burn to make a point to the rest of the squad? He didn't just kick two players out, he kicked them out of the first team, refused to let them go to the club xmas party IIRC.
Considering it's the same problems he had at Chelsea, and he's repeating them all, I find it hard to blame anyone except AVB... and LEvy for ignoring what he did at Chelsea.
