If United lose their No1, reports suggest Oblak would be the first-choice replacement, says The Sun.
The Slovenia international, 26, has been with Atleti since 2014. In that time he has developed into one of the best goalkeepers in the world, working alongside a brilliant defence organised by Diego Simeone.
The stats are really rather impressive - from 156 La Liga appearances, Oblak has conceded just 96 goals and kept 90 clean sheets, making 385 saves at a percentage of 79.8.
With ex-Atletico man De Gea far from his best last season, an in-form Oblak is arguably an improvement on the Spaniard, who has won United's Player of the Season award four times.
