The Bosnian, who has been one of the outstanding keepers in England this season, has been linked with a host of European clubs.
However, the former Portsmouth goalkeeper has claimed that he is not "thinking a lot about speculation".
"I'm not thinking a lot about speculation. I have a lot of work to do at Stoke City, we have to stay in the league," he told Sky Sports News.
"But I'm not running away from it, everybody is happy when he is linked with such clubs as Arsenal, Manchester United, Liverpool - I'm glad my name is mentioned in these stories because this is the proof that I'm doing well.
"We will see what will happen at the end of the season. But for now the most important thing for us is survival."
Stoke currently sit 15th in the table, six points from the drop zone.
