MATCH FACTSHead-to-head•The two clubs have only met once before in the League Cup: Liverpool ran out 2-1 winners in a fourth-round tie at Anfield in October 2007.
•Cardiff have won twice as many games as Liverpool in this fixture (18 wins to nine), with two matches drawn.
•Their 29 previous encounters have yielded 95 goals - an average of 3.2 goals per game. There has never been a goalless draw between the two clubs.
Cardiff•Cardiff, appearing in their first League Cup final, have become the 16th club from outside the top flight to reach the final, and the first since Birmingham in 2001, who incidentally were beaten by Liverpool.
•City's Carling Cup adventure has so far lasted 750 minutes, with four of their seven matches going to extra-time. Two of their victories came courtesy of penalty shoot-outs.
•The Bluebirds have beaten one Premier League side, three from the Championship, one from League One and one from League Two to reach the final.
