AVB will have worked with Carvalho at Chelsea. Apart from being a wiley old fox of a defender (although IMO he's way past his best) he'd also be AVB's dressing room capo as well maybe. A strong character, used to the EPL, iused to EPL players, who could be AVB's eyes and ears at ground level.
Dressing room capo, and coach if he wants it in a sesaon or two?
Fwiw AVB is less than a year older than Carvalho.
I'm distinctly underwhelmed with the idea of Freund as our new Number 2. As a player he was like Sherwood, but worse, and the "football genius" gag was always pure irony from the club of Hoddle and Ardiles.
Maybe the real "football genius" coach is this Luis Martins character...
