Shea has struggled to make an impact at the Britannia Stadium since his January arrival from Dallas and he featured just twice as a substitute in the Premier League last season.
His only appearance this term was a 45-minute run-out against Walsall in the Capital One Cup and a potential loan to Derby collapsed after Nigel Clough was sacked as manager.
The 23-year-old is hoping Stoke boss Mark Hughes will soon give him an indication of whether he will be considered for first-team selection, or will be allowed to head out on loan.
"Birds were chirping," Shea said in The Sentinel regarding the possibility of joining Derby. "There was word, but obviously he (Clough) got sacked.
"I've got to get playing, whether here or on loan somewhere. It's up to the gaffer and hopefully he tells me something soon.
"If I'm not going to play here, I want to go out and get some games in. But I can't control that, that's up to them.
"My body feels good and my mind feels good. A few weeks ago I was struggling because I was frustrated, but I feel better now.
"Andy Wilkinson went in and played well on Saturday and so hopefully when my chance comes I can do the same."
