Despite not hitting the heights they did last season, Villa did their utmost to try and get ex-Leeds United player Ward to stay at the West Midlands club.
Monchi added: “Carla came to us a few weeks ago and spoke of her plan to step down. We have had extensive dialogue with her to see if there was anything we could do to persuade her to stay, but she is adamant that she wants to take a break from the game. Therefore, on behalf of everybody at Aston Villa, I want to place on record our grateful thanks to Carla for everything she has achieved with us and wish her well for the future.”
