Lifelong Atleti supporter and season-ticket holder Juanjo Mendoza gives the lowdown to our much-loved matchday programme United Review, which you can order here.
How do you feel ahead of the second leg?
"Optimistic. We're on a good run. Atleti haven't played well this year, but going to Manchester with a 1-1 first leg scoreline and with no away goals counting double gives us a lot of options. We were expecting a strong United but, honestly, I didn't think they were the better team in the first leg. Getting to the round of 16 was something of an unexpected bonus given the nature of how we qualified, so I'm also approaching the game with a lot of peace of mind.
