Other notable ties during the group stage include Liverpool facing Sevilla twice after the Spanish side beat the Reds handsomely in the 2016 Europa League final. Liverpool aren't the only English squad to run into some familiar faces, though.

The Welshman left north London for the Spanish capital in a world-record deal in 2013 and has since won this tournament three times.

Elsewhere, there is another rematch of a recent European final in Group D, with Juve getting two chances for revenge after losing 3-1 to Barca in 2015's showpiece game.
