If you guys bottle it again ...
There is a big chance it can happen. Losing to that MU side, in that fashion (they didn't even tried to attack), tells you that anything is possible.
As the other guy said, this is a game with two weak defences and two great attacks. The most clinical team will win this tie.
Juventus are facing Lyon who are worse this year. Juve should win this. Anything else would be a disaster. No Memphis either.
Lyon is 10th in the weakest L1 of recent years. They are really shit. The weakest team left in the competition. Juventus will win without breaking a sweat.
