The Serbian has been linked with Barcelona and AC Milan this summer.
“I’ve never said anything about Barcelona or Real Madrid or AC Milan – or any club,” he said.
“I never speak about my future so I don’t know why someone else does. I showed at Wigan on the pitch how happy I am at this club.
“Any fan of United only has to see how I played to know how committed I am. I spoke with my agent about this and what he said. I know about all the rumours about me but I don’t want it to have an impact on the club.
“It’s not a good time for my club to be hearing those rumours.”
“It’s not true that my wife is not happy,” he continued. “I don’t know how that rumour came out, she’s not what you’d call a famous wife. She’s never spoken to a newspaper.”
