Coach: Jurgen Klopp
Star man: Robert Lewandowski
Previous best in CL/European Cup: Winners 1997
Chances: Caught the eye in the group stage and are being tipped as dark horses for the title with their dynamic attacking play. Klopp's tactical blueprint has made him a reported summer target for Chelsea.

Chances: Over a decade on from Real's last Champions League triumph, victory over Manchester United must have given Real added belief that they can secure their 10th European crown. If, as has been speculated, this does prove to be Mourinho's last season at the Bernabeu, he would love to go out by claiming a third Champions League title, each with a different club having also triumphed with Porto and Inter Milan.
Did you know? Real appeared in eight of the first 11 European Cup finals.
Who will win the Champions League?
Paris St Germain
