Butland spent the second-half of last season on-loan at Birmingham City.
Gary Mellor told 6 Towns Radio: "We have to weigh up all possibilities and I have to keep him playing so if Asmir is still here on September 2nd I'm hopeful that Jack isn't. I don't see him sitting on the bench at Stoke City.
"Mark Hughes might see that differently and that's when Stoke and I do have issues. I have to keep Jack playing so that his international ambitions are on track and he continues to develop. There's nothing like actual games to help you develop, especially as a young goalkeeper."
