Still very popular at the club and sounds just what we need
‘It’s the bubbliness that Brennan alludes to which is why current Villa manager Bruce is happy to have him around his squad despite the fact that he hasn’t played for so long.
Youngsters Andre Green, Corey Blackett-Taylor and Callum O’Hare have all made their first team breakthroughs over the course of Richards' time at the club and the experienced defender is understood to have been instrumental in their transition from the under-23 to first team dressing room.
Richards’ words of advice haven't gone unnoticed, and he remains a popular figure with the senior pros too.
He is often at the centre of dressing room banter. Social media accounts have shown him keeping fit with boxing training, and he has taken part in team-bonding sessions away from the training ground.’
Chances - nil.
