Solskjaer coached Tunnicliffe inside United's academy.
He said, "Yeah, I noticed he wasn't in the squad this latest league game. Hopefully he's not injured and hopefully we'll see Ryan. I had him in the Reserves and I'm glad to see he's having a career. He was always an attacking midfielder, going from box to box, and it's always good to see them back.
"The Academy is fantastic, from when we get them in at an early age. We make sure they get careers as well. Ryan was close to making it here but it just didn't happen for him. I'm happy to see the likes of him and other players make good careers somewhere else."
