Antoine Griezmann has denied a report that he is set to join Barcelona this summer.

Telefoot claimed on Sunday that Barcelona are ready to pay the €200 million release clause in the 27-year-old's contract.

"It's not good information," Griezmann said.

Griezmann admitted transfer rumors have taken their toll.

"It was because of what I said [about Manchester United]. I didn't express myself well. I made mistakes," he explained. "After that, I came back strongly physically and mentally I was fresher. Since January, I've been pulling up trees, let's hope I continue like that."
