Tonight will be our eighth Champions League group stage fixture in Spain against the fifth team from that country, but how much do you know about those previous visits?
We travel to the Estadio Ramon Sanchez Pizjuan for that eighth Champions League group stage tie in Spain against Sevilla, a match that could go a long way to deciding who finishes top of Group E. Both sides have already secured their places in the knockout rounds and are currently level on 10 points, with no clear leader on head-to-head following our 0-0 draw at Stamford Bridge.
It isn't the first time that a match against Spanish opposition has played a key role in deciding the outcome of our Champions League group, though. Can you remember how those seven other away fixtures turned out and what it meant for our chances of reaching the next stage? Find out in our quiz. Good luck!
