Former PSG captain and France international Sakho is being linked with a summer move to OL.
Asked about the rumours, Aulas referred reporters to OL sports chief Juninho, before admitting he's a fan.
"See Juninho. I don't know if the track is hot, but it's up to him to say," he told Canal Football Club.
"I really like Mamadou because he has the right personality, now there are also other very high level tracks, so it's up to the coaches to choose."
