Glen Roader ?

Is he still involved ?

Hope not. He reminds me of Alan Partridge.

Didn't he advise Tan on the Russell Slade appointment

If it was him who "advised" Tan to appoint Slade then if he is still involved in the club he must be keeping his head well down.

More likely he charged a fat "consultancy" fee for his f*cking useless advice and is now pissing himself laughing on a beach somewhere.
