Thommo was Houllier's No2 at Anfield and the pair were together again for Jamie Carragher's testimonial.
Looking tanned and healthy, Houllier simply gave a Gallic shrug and shook his head when asked about the state of his health.
But former Liverpool manager Thompson - a close ally of Houllier in the past - pushed the Frenchman's cause.
He said: "Have you seen him? He looks extremely fit and what he would bring to Aston Villa is a wealth of experience and organisational ability in the role.
"You see what he did for the golden generation of French football - not the latest group of French players, those who came before."
