The France international is a priority target for the Red Devils this summer, and it is claimed that the club already agreed the finances over his contract with his representatives back in January.
United are now just eager to ensure the saga does not drag on for too long, as it did with signing Paul Pogba from Juventus last summer, and have a deadline in mind for the deal to go through.
According to the Independent, United want Griezmann signed, sealed and delivered by the end of next month in what could be a busy summer with a number of new arrivals.
The report claims that United are hoping to improve their image in terms of operating an efficient business model, having struggled to get high-profile deals over the line in recent years.
The signing of Griezmann would be a great way to kick things off this summer, with Jose Mourinho’s side in urgent need of additions up front due to doubts over the futures of Zlatan Ibrahimovic and Wayne Rooney.
The 26-year-old has sent mixed messages over his future over the past few days, first suggesting he rated his chances of joining United at ‘6 out of 10’ before seeming to backtrack on the prospect of leaving Atletico.
‘I’m very happy with the support of the people, the fans, the team-mates. It’s been a great year and I hope I can get better every year and win trophies with this team. I will do everything possible,’ he was quoted as saying today.
