West Brom goalkeeper Sam Johnstone is happy seeing Rich Hartis back at Manchester United.
Johnstone worked with the goalkeeper coach while with United.
He told Sky Sports: "He's a friend as well as a former coach.
"He was a key part to my development. At that age, growing up at a club like United, he drilled in all the basic stuff and was on at me about what I had to do away from the training ground. It's crazy really because at that age he always said he could see something there. He got close with my Dad and said, 'He's got the size, he's still going to grow, we just need to get all the basics like footwork, handling and timing drilled into him.'
"So Rich was massive for me and when he left I was quite upset, to be fair. When we went to play them at Old Trafford this season, we stood in the tunnel for about an hour after the game just talking. He knew what I had done in the games I'd played, what I needed to improve on and he still keeps an eye on what I'm doing which is nice."
