After seeing his side ease past Bayer Leverkusen in the last 16, Blanc admits that he is eager to be be drawn against his former side, who produced a second-leg fightback to knock out Olympiacos on Wednesday evening.
"It would be nice to face Manchester," Blanc, who played for United between 2001 and 2003, told reporters.
"Their qualification I am sincerely pleased for because they live in difficult moments, they were able to regroup and there should certainly be an amazing atmosphere.
"It would make me happy to visit Old Trafford as it would make me happy to visit other stadia."
The draw for the quarter-finals will take place in Nyon on Friday.
