For Manchester united to beat Lyon in this quarter finals is going to be a very big deal for them, because Manchester united is not in condition they are find it difficult in times of securing victory. Although sometimes they normally surprises their fans, but one thing I believe is that if Manchester united finally wins Lyon in this game, I think they most likely qualify to the final.
It will not be easy for Manchester United to beat Lyon and this will be an away game for Manchester United so Amorim will definitely try to play it safe. Getting a draw will be an advantage for Manchester United because later in the second leg they can try to take advantage of the home game to get a win. Lyon themselves must be aware of the surprise that will occur because getting a draw will not be beneficial for Lyon.
In the previous few matches Manchester United started to improve and they started to find a much more consistent rhythm of play, although overall it has not fully improved. Manchester United could be a serious threat to Lyon if they do not dampen the attack pattern that Amorim's team is trying to launch.
