Meh, I think Real would be way too experienced and savvy for us. Just imagine Asensio or Ronaldo against Gomez or Alexander-Arnold with Marcelo going up and down the sideline the entire game. Porto were atrocious (and still we were lucky not to concede on two occasions), but Real would capitalize on our defensive issues.
We can score in any game so I'd back us to score one or maybe two away goals against basically any side (not saying we will but it's possible), but still... I'd rather get the likes of Roma, Shakhtar or Sevilla next round - a good chance to reach the semis of the CL which would be glorious. No one except rival fans will remember the path to the finals if you get there.
