Mikel Arteta kept his domestic cup record intact as Arsenal proceeded to the last eight of the Carabao Cup on penalties, Joe Willock scoring the crucial kick in the sudden-death phase after Harry Wilson had seen his effort saved. That was hard on Wilson, making his first Anfield start after several seasons on loan, though Divock Origi and Mohamed Elneny also had penalties saved and the Arsenal goalkeeper Bernd Leno deserved something for his saves in normal time that took the contest to a shootout. Liverpool and Arsenal must be tired of meeting each other, or perhaps they are just tired. Despite being altered beyond recognition from their Premier League meeting at Anfield on Monday, these two shadow squads did little more than shadow-box for the 90 minutes of normal time. Arsenal might have taken an early lead when Eddie Nketiah found himself with a shooting chance on the six-yard line after eight minutes, though he hesitated a fraction too long and Adrián was able to extend an arm to flick the ball away from his feet. While both sides made wholesale changes Arsenal had a slight edge in experience. They had the new England call-up Bukayo Saka at left wing-back and it was a foul on the teenager that earned Takumi Minamino the first booking. When Minamino brought down Nicolas Pépé after losing the ball on the half hour he was therefore living dangerously, though Kevin Friend contented himself with only a word of warning. Mohamed Salah, one of the few survivors from Liverpool’s 3-1 win three days before, was probably their most dangerous attacker in an uneventful first half. For the most part Saka looked after the striker quite well when he stayed on the wing, it was his regular incursions infield that seemed most likely to cause Arsenal problems, though he clearly does not share the same sort of understanding with Diogo Jota and Minamino that he enjoys with Roberto Firmino and Sadio Mané. All the drama in the first half was packed into its final minute. First Dani Ceballos got away with a rash tackle on Jota that must have been outside the area by a matter of millimetres, then when Arsenal failed to clear the free-kick a Jota header brought a one-handed save from Leno, with Minamino arriving at speed to volley the rebound against the bar. It was a clear chance but a difficult one, with the ball at an awkward height and Minamino having no time to readjust his position. While Liverpool had probably applied more pressure to their opponents’ goal than Arsenal had managed, in terms of scoring opportunities neither side had looked particularly threatening. Leno came to Arsenal’s rescue again at the start of the second half when a corner fell to Virgil van Dijk and he stabbed a shot goalwards from a couple of yards out. There was no great power in the effort but it was heading for the bottom corner until the goalkeeper got down smartly to his right to push it away. Jota hit a deflected shot wide and Marko Grujic headed the wrong side of a post then brought another save from Leno as Liverpool began to dominate, at which point Jürgen Klopp stuck to his original plan and brought off Salah and Van Dijk after an hour, removing the only two outfield players who had started the previous game. The pattern did not change, Leno was still needed to keep out attempts by Jota and Grujic, and if anything Liverpool stepped up their pressing game with Origi on the pitch, yet an excellent covering tackle by Neco Williams was necessary to prevent Saka opening the scoring against the run of play. Pépé and Nketiah also had chances and Willock had a penalty appeal turned down in stoppage time.
