For either Manchester City or Real Madrid, its Champions League quest ends Friday.
The two powers meet in the second leg of the round of 16, more than five months after Man City won the first leg, 2-1, in Madrid to take the advantage in the tie.
Plenty has transpired since to change the calculus, though, with Real Madrid resurgence after La Liga's restart culminating in 10 straight wins and the domestic title, while Man City capped a second-place finish in the Premier League.
Both sides will be without some key contributors, with Man City still without injured striker Sergio Aguero.
