Did you know?10 interesting stats and facts ahead of Liverpool v Arsenal
This is Liverpool's 18th League Cup semi-final. Only Tottenham Hotspur (19) have appeared in more.
There has been only one previous semi-final meeting between the clubs in the League Cup, with Liverpool winning 2-1 over two legs in 1978. All the goals came in the first leg at Anfield as Kenny Dalglish and Ray Kennedy were on target.
This will be the first occasion in League Cup history that Liverpool have faced the same club in three successive seasons.
The Reds have played seven previous semi-final first legs at home in this competition, winning five and drawing two.
Liverpool have lost only one of the 15 semi-final first legs they have played at Anfield in any competition – that came in the 1970-71 Fairs Cup when they lost 1-0 to Leeds United.
If Takumi Minamino scores he will become only the fifth player to net in four successive Liverpool games in the competition, following Dalglish in 1980, Ian Rush (1982), Steve McMahon (1986) and Vladimir Smicer (2000-01).
In 21 League Cup games under Jürgen Klopp, 78 different players have been used – the last being Billy Koumetio in the win against Leicester City in the previous round.
Three Reds players have started all three League Cup fixtures this season: Joe Gomez, Alex Oxlade-Chamberlain and Minamino.
Twice before Liverpool have defeated Arsenal and gone on to lift the League Cup. They won 3-0 in a fourth-round replay at Anfield in 1981-82, and in 1994-95 Rush scored the only goal in a quarter-final clash.
Alisson Becker and Thiago Alcantara are yet to play their first game for the club in the League Cup.
