Ludogorets v LFC: Pre-match stat pack
Ludogorets Razgrad are the opponents as Liverpool seek to boost their hopes of reaching the Champions League knockout stages this evening - here are the vital pre-match facts and figures ahead of kick-off.
Liverpool's record in the European Cup to date shows 179 fixtures, with 102 wins, 37 draws and 40 defeats.
A victory this evening would guarantee European football into 2015, as it will mean the Reds can finish no lower than third in Group B.
Three points in Bulgaria would also keep qualification to the knockout stages in their own hands, with a subsequent win over FC Basel by two clear goals - or a victory of any kind, if the Swiss side do not beat Real Madrid - sufficient for progress.
Six teams in Champions League history have taken three points from their opening four group games and still qualified for the next phase.
Ludogorets are the third Bulgarian side Liverpool have faced in European competition, following meetings with CSKA Sofia and Levski Sofia - the Reds have won seven and lost two of those games.
In Bulgaria, the Reds have won three and lost one of their four visits - all at the venue for tonight's fixture, the Vasil Levski Stadium in Sofia.
Graeme Souness is the only Liverpool player ever to score a hat-trick against a Bulgarian team, hitting three in a 5-1 victory over CSKA Sofia in 1981.
Steven Gerrard was the last Red to score a European treble, doing so as a substitute against Napoli at Anfield in the Europa League in 2010. It was one of 17 hat-tricks recorded by the club in Europe.
Liverpool are two goals short of recording 200 in European football as the away team, excluding games played at neutral venues.
The Reds' last away win in the Champions League came at Debrecen five years ago this week, when David Ngog scored the only goal of the game.
Ludogorets have played 13 times at home this season, winning nine - with only Real leaving with a victory.
The Bulgarians have kept four clean sheets in their last six games in all competitions, and have scored in all but two of their last 17 contests in league and cup.
Coach Georgi Dermendzhiev has been in charge of Ludogorets since August and the former academy director has presided over 23 matches in league and cup, winning 13 and losing five.
