The 26-year-old Oblak is said to want to play in the Premier League.
The Slovenia global has been heavily linked with a move to Ole Gunnar Solskjaer's side this summer following David De Gea's decision to leave Old Trafford.
Oblak signed a contract extension with Atletico in April, with his deal running until the summer of 2023.
Oblak has become one of the best goalkeepers in world football since joining Atletico from Benfica in 2014 with his sensational performances between the sticks helping Diego Simeone's side forge a reputation for having one of the meanest defences in Europe.More news: Amitabh Bachchan's Twitter hacked: Pak PM's profile picture, 'Love Pakistan' in bio
The Slovenian has won LaLiga's Golden Glove award in each of the past four seasons, and was also named in the UEFA Champions League Squad of the Season in 2015/16 and 2017/18.
Last season, the Atletico goalkeeper missed just one league outing and conceded 27 goals, with the club boasting the best goals conceded record in the league by far.
