This will be the first occasion in League Cup history that Liverpool have faced the same club in three successive seasons and only the fourth time in any competition.
The last two clashes in this competition have been decided by a penalty shoot-out, but Liverpool have won each of the last six Anfield league meetings.
And if he scores tonight he will become only the fifth player to score in four successive Liverpool games in the competition following Kenny Dalglish in 1980, Ian Rush (1982), Steve McMahon (1986) and Vladimir Smicer in 2000/01.
League Cup Unpredictability
Rocky on the Road
Eddie Nketiah has seven goals in eight League Cup appearances for the Gunners and all five of his goals this season have come in this competition (in the last three rounds).
Arsenal have won five of their 12 away games in all competitions this season, losing six.
Lucky charm Oliver?
Michael Oliver has refereed a game between the teams six times previously – Liverpool have never lost thanks to a record of four wins and two draws.
He was in charge of the Anfield meeting in November – Liverpool won 4-0. Today he takes charge of a Liverpool game for the 50th time.
