Of the eight European Cup semi-finals reached by Liverpool, they have won seven. But, to have any chance of reaching another Champions League final, the Reds must score at Chelsea and beat history.
Liverpool have not scored an away goal in a European semi-final since 1985, when they beat Panathinaikos 1-0.
Liverpool have scored in nine of their last 10 Champions League away games. But the only exception was against, of all teams, Chelsea last season.
Good for Blues
Liverpool's Jamie Carragher and Steven Gerrard will miss the final if they get booked today. Defender John Terry is the only one at risk for Chelsea.
Chelsea have a record of 12 clean sheets in their last 16 European home games, including the last four.
In five previous European home games against English teams, Chelsea have conceded only once - against Arsenal in the 1-1 draw in the 2004 quarter-finals.
The Blues have not lost any of their previous eight European semi-final home games.
