The Australian international is now with League One club Chesterfield.
The Australian international had been with the club for ten years after heading over from Australia as a 16-year-old and at one point looked like a future star of the first-team.
But injuries took their toll on the player. After spells with Port Vale, Wycombe Wanderers, Lincoln City, Bolton and Wigan Athletic on loan he left in the summer - joining Chesterfield on a free.
This week the 26-year-old has been discussing his exit from Villa to FourFourTwo Australia - admitting it was a tough but necessary decision:
“It was just the way the football was going.
“It was the right time for me to part from Villa, and you could sort of say kick-start my career again. I’m feeling, touch-wood, quite good so hopefully I remain fit and play as many games as I can.
“I had a great time there, I had some great coaches. It’s a good club and they bred a lot of players through. Nothing but good things to say about my time there.”
Herd, who play across the back four and in holding midfield, featured 42 times for Aston Villa and scored twice but by the time he had left in the summer he had not played a game for Villa since a 2-1 defeant against Stoke City in December 2013.
He has played 10 times this season for The Spireites, who have their eye on promotion to the Championship this season and currently sit four points off the play-off spots.
Herd is contracted with the club until January and he will then be hoping to sign an extension and help them in their promotion hunt.
