Aubameyang has been an effervescent force for Dortmund since arriving from Saint Etienne in 2013, netting 126 goals in 195 games in all competitions.
Varane was signed by Mourinho at Madrid in 2011 and has gone on to make 192 appearances for Los Blancos; the Portuguese made an unsuccessful attempt to sign him again last year.
And Saha, speaking earlier this week, has encouraged the 54-year-old to make advances for the pair during next year’s transfer window.
“Varane is a great defender and I think he would bring something special to the defence. And Pierre-Emerick Aubameyang, he’s very quick and he’s got the eye for the ball all the time
“He’s really impressed me in the last few years. And he’s still a player you feel is still stepping up. He really wants to improve. I think he would be a good addition.”
But he hasn’t repeated such feats at centre-back. The 54-year-old is by no means short of options at the back but still lacks that commanding, internationally revered, world class defender at the peak of his powers so vital to any successful side. Needless to say, there aren’t many better candidates than the man he signed from Lens as a youngster six years ago.
As for Aubameyang, prizing him away from the Bundesliga would be difficult: Dortmund showed through Ousmane Dembele that any club looking to sign their best players will need to shell out a sum way beyond £100m, and Mourinho may feel inclined to pour his resources into signing either Antoine Griezmann or Gareth Bale instead.
