Warrington, sidelined with a shoulder injury, has heaped praise on the 23 year-old.
He told the Star:"When I was at York City he joined the club as a youth team player and he did really well. Last season I thought he was fantastic, I voted him as my professional of the season.
"The gaffer wanted to get somebody as quickly as possible - and from what I've been told he had a good game at Exeter.
"I really wish him the best of luck. We have a squad policy at the club and, whoever comes in, they all have a part to play."
Elsehwere, Warrington is hoping to be back in action himself sooner rather than later, and added: "I got told I'd be out for two months, but to be honest I'm hoping to be back after a month. I'm still training hard, working on my technique, although I can't do any diving.
"My shoulder doesn't feel too bad, hopefully the ligaments heal quickly. I want to get back playing as quickly as possible.
"It's just one of those things unfortunately. I fell awkwardly, I piledrived the floor and my shoulder took the full force of the fall. I was lucky I managed to get my neck out of the way, otherwise it could have been a lot worse.
"It's going to be frustrating on the sidelines, but I'll be working hard in the gym to get back as quickly as I can."
