The fantastic early strike by Pierre-Emerick Aubameyang handed Arsenal the lead and they kept on at Wembley for a long time, before sub-Takumi Minamino took his chance and converted from close up to draw Liverpool level.
Joe Willock went closest to a winner but with five minutes remaining, he couldn’t guide a free header on goal, not that it counted in the long run.
Twice Sadio Mane had been thwarted by Martinez speeding off his line to smother his attempts.
Salah just couldn’t get involved in the game but it wasn’t because of a lack of trying. He had to abandon the right flank to try to find opportunities as he tried to make an impression but he was kept very quiet by Arsenal’s robust defence.
Rhian Brewster was the only player to miss in stop-time as he blasted his shot against the crossbar and Aubameyang netted the final pen to send the Gunners a 5-4 spot win.
