Tony Parks
AVB learnt his trade analysing other teams play. Preparing Morino's scouting charts etc. His is someone who is good at analysing things. He's not a big talker. He's more contemplative. A tactician. Not that it shows currently.
There's no evidence of him being good at analysing at all, he lines up the team in the same regardless of who the opposition are, it was the biggest complaint about him last year by Chelsea fans and he's doing exactly the same thing his season.
You're right about him not being a good communicator, a failure which is totally incompatible with being a top class manager.
