The Stoke keeper admits he has ambitions to play at the top level but said he has had no contact with the aforementioned clubs.
The 26-year-old Bosnian said: "There is no truth as far as I'm aware. I've not had contact with either club.
"From my point of view it's flattering to hear those words - two of the biggest clubs in the world - but I'm just enjoying playing my football here.
"I focus on my job each and every day and make sure I perform every weekend for Stoke City.
"I've enjoyed my time here and don't want that to change but everyone has ambitions to go as far in the game as possible but there's been no contact.
"I want to test myself against the best players in the world and to qualify for the World Cup this year with Bosnia is a huge achievement.
"It's something I'm looking forward to and I'm just trying to progress my game and improve."
