The 25-year old Bosnian international admits he is humbled by interest from the Premier League leaders but says he is content at the Britannia Stadium at this point of his career.
"I'm not under more pressure because United is watching me, I'm glad that they do because that means I'm doing something good. It gives me more motivation to do better and better," he told Sport.ba.
"I'm pleased that the big clubs are interested in me, but as I said many times - I'm happy at Stoke City because they gave me a chance to play in Premier League.
"We will see what will happen in the summer. In football you can never know 100 per cent what will happen."
