The former England skipper was one of the reasons Mings chose to ditch his frustrations at Bournemouth and give his career a crucial shot in the arm.
He admits the move will have proved to be just perfect if Aston Villa clamber back into the Premier League by beating Derby at Wembley.
Mings explains: “We've sat down many times and his overriding comments to me are to go through the game without being seen. He tells me that a lot.
“Those little bits of information are obviously great. Your job is to go under the radar and keep the ball out of the net.
“If you do that and let the strikers get all the adulation and the headlines, then you're probably doing your job."
He adds: “Obviously when I knew that there was a chance that I could come here and learn from someone like John, in my position, it was an opportunity I couldn't really turn down.
“We sit down after my games and go through clips and work out on the training pitch together, so he's been a big help."
