"What matters is the team and all of us being focused on what we need to focus on, which is winning games, rather than contracts or any topics that can be a distraction. What matters is focusing on football.

"You don't have time to think about things that aren't as important as football and the points that are at stake in the games that we have to win and do well in."

In August, United were positive over the chance of De Gea renewing his deal, but Juventus have reportedly targeted external-link the Spain international as another low-cost high-quality addition after picking up Liverpool midfielder Emre Can, Barcelona full-back Dani Alves, Bayern Munich midfielder Sami Khedira and Athletic Bilbao striker Fernando Llorente on free transfers in recent years.

"I've been at the club for eight seasons now. I'm very happy here," said the keeper, who has been the Premier League club's player of the year for the past four years.

"I always feel that warmth from the fans and everyone who works at the club."
