Shea's agent Gary Mellor insists his client is ready to make an impact next season.
Mellor told The Sentinel: "Brek is getting fitter all the time, he is training hard and putting the work in. In fact, he played that under-21 game after a full afternoon training session.
"He's hoping that he gets a chance to prove he can do a job. Tony [Pulis] is well documented in saying that he is looking to next season for Brek, but Brek is still hopeful that he can get a chance at some stage this season."
