Live updates:
16:35 CET - One man who could make all the difference today is Alexander Isak. The Swedish striker has begun to get into his stride after a difficult first season at Liverpool and, crucially for Iraola, he is scoring goals.
Isak has scored in his last two Premier League games and six goals in seven league appearances. If Liverpool are to win this, expect the in-form striker to play a big part in it.
16:16 CET - Team news is in from Anfield! As expected, Arsenal are without Bukayo Saka as Arteta starts Noni Madueke and, surprisingly, Christos Tzolis on the wings and Kai Havertz up top.
As for Liverpool, Iraola has made just one change from the side that beat Brighton last weekend and it is a surprising one! After evidently impressing Iraola in the Carabao Cup midweek, exciting 19-year-old midfielder Trey Nyoni starts instead of Ryan Gravenberch.
16:45 CET - Liverpool might just fancy their chances at Anfield due to their imperious home record against the Gunners.
Liverpool are unbeaten in their last 13 league meetings with Arsenal at Anfield and, given their strong form in all competitions, Iraola's side will fancy their chances of keeping that record going this evening.
However, Arsenal are the Premier League holders for a reason and despite their midweek setback in the EFL Cup, Arteta's side are still in very impressive form domestically and in Europe - so they will be no pushovers.
15:30 CET - Welcome to Flashscore's live coverage of a box-office clash between Liverpool and Arsenal this afternoon!
Arsenal and Liverpool are old rivals, and it is always an important meeting when they go to battle, but this one feels huge.
The Gunners are the Premier League holders and favourites, but a trip to Anfield is rarely an easy assignment, and Andoni Iraola's Liverpool have just started to find some form after winning their last five games in all competitions.
Meanwhile, all was rosy at Arsenal before they were stunned by League Two Fleetwood in the EFL Cup midweek, leaving some unpredictability about this fixture.
Kick-off is at 17:30 CET, and we'll be posting the team news and live updates throughout the match right here.
