Arsenal
Emi Martinez – 8: Commanding showing between the posts for the Gunners. Saved well when Mane was put through early in the second half and denied the winger again one-on-one later.
Hector Bellerin – 6: Looked slightly off the pace early on but grew into the game before being subbed shortly before the hour mark.
David Luiz – 7: Experience came in handy during the spells in which Liverpool put pressure on the Arsenal defence in the north London side’s box. Scored his penalty confidently.
Rob Holding – 7: Had the measure of Mane for most of the first half, especially when defending long balls from the Liverpool defence, but was troubled a bit more in the latter period.
Kieran Tierney – 7: Was tested early on by a threatening Robertson cross, and just about dealt with it. After that, the Scot impressed with an energetic and smart display.
Ainsley Maitland-Niles – 7: Very little to criticise in the case of the left wing-back, who looks to be improving and was very disciplined here. Scored calmly in the shootout.
Mohamed Elneny – 7: Seemed comfortable alongside Xhaka in the Egypt international’s first competitive game since returning from loan at Besiktas.
Granit Xhaka – 7: Strong and tidy in the middle of the pitch. Has seemed much more consistent since Arteta’s arrival.
Bukayo Saka – 8: Picturesque crossfield ball from the 18-year-old helped to set up Aubameyang’s brilliant strike on 12 minutes. Showed composure beyond his years from start to finish.
Eddie Nketiah – 7: Worked hard throughout. Was denied a goal by a strong Alisson save.
Pierre-Emerick Aubameyang – 9: Found the net with a stunning, dead-eye finish in the first half to put Arsenal ahead. Looks so at home at Wembley. Fantastic penalty in the shootout.
Liverpool
Alisson – 7: Had no chance of stopping Aubameyang’s opener. Elsewhere was dependable as usual, as shown when he kept out Nketiah well when Liverpool trailed 1-0.
Neco Williams – 6: Looked a little out of sorts as Aubameyang ran at the right-back before whipping a finish into the far bottom corner, but elsewhere the 19-year-old put on an encouraging display before leaving the field on 60 minutes.
Joe Gomez – 6: Not a poor performance by the centre-back by any means, though his still appears to be a position that could be strengthened in the long run.
Virgil van Dijk – 7: Generally marshalled Nketiah well. Turned home a Robertson free-kick but was caught offside.
Andy Robertson – 8: Terrific crossing troubled Arsenal on a number of occasions. Provided plenty of energy as expected.
James Milner – 8: Was as industrious as you’d expect. Liverpool’s best player for the hour that he was on the pitch.
Fabinho – 6: Failed to really impose himself in midfield. Scored his penalty.
Georginio Wijnaldum – 6: Another player whom the game seemed to pass by – until Arsenal tired, that is.
Mohamed Salah – 6: Unusually anonymous for Jurgen Klopp’s team in the first half but became more spirited after the break. Netted his penalty with conviction in the shootout.
Roberto Firmino – 7: More inventive than his forward partners for the most part, the Brazilian began to impact the game more as it went on.
Sadio Mane – 7: Was largely kept in check by Holding in the opening half, but became more of a nuisance as the match wore on.
Takumi Minamino – 7: Couldn’t miss the equaliser but deserved it after a bright showing following his arrival in the second half. Scored his penalty.
