Juventus attacker Douglas Costa has blasted claims he was in talks with Manchester United this summer.

Costa was upset by reports from an agent that he was close to joining United.

“I'm writing to deny the baseless news published today, which said I was in negotiations with some clubs during the last transfer window," wrote the 28-year-old on Instagram.

“Since the start of this season, I've been clear that I wanted to stay here to win trophies and give blood for the Juve jersey.

“Junior Mendoza is my only agent and the only person authorised to speak on my behalf."
