In case you missed it...
In between the two legs, Barcelona boss Luis Enrique announced he will step down at the end of the season as he needs to "rest".
The 46-year-old joined the club in 2014 and had led them to eight trophy victories.
"It is a difficult, measured and well thought-out decision and I think I have to be loyal to what I think," said Enrique.
"I think it will be good for me at the end of the season, because I need to rest. That's the principle motive."

What odds on something similar from Unai Emery's men tonight?
Barca have progressed past the round of 16 in each of the last nine seasons, the longest run ever in the competition, but that record looks like disappearing, unless...!
