Roma will be attempting to pull off another miracle by coming from 5-2 down to book their place in the final in Kiev, where they would face Real Madrid.
However, much of the build-up to the game has surrounded the safety of fans in the Italian capital after 53-year-old Liverpool fan Sean Cox was left in a critical condition after being attacked by Roma fans outside Anfield last week.
The Serie A club have done all they can to distance themselves from those involved with their president publicly criticising them, while the hand of friendship has been extended over the last week with players pictured on Thursday training in shirts with the words 'Forza Sean' on them.
"Great, great, great gesture. I already thought they showed a great gesture before training at Anfield at the memorial for the 96," said Klopp, referencing Roma's laying a wreath in memory of the Hillsborough victims a week ago.
"It is a really nice thing and in these moments at least football fans should stay together and show this kind of respect."
