The goalkeeper, who has been capped by England, has struggled to break into the Stoke team since his £3.5million move from Birmingham City in January 2013.
Butland has since impressed while out on loan at Sky Bet Championship sides Barnsley and Leeds United.
Butland became England's youngest-ever goalkeeper when he made his international debut in a friendly against Italy in 2012.
And the 21-year-old admits first-team football is vital for him next season as he looks to continue his development.
"I want to be playing in the Premier League," said Butland.
"If Asmir stays and I'm not playing, a loan is massively important."
