36' Salah looks to be through on goal once again after darting through the Arsenal defence and into the path of a Firmino through-ball, but, once again, the linesman's flag denies the Egyptian an opportunity to test Cech from close range.
35' The corner is just about dealt with by the visitors, allowing them to push forward on a rare foray into the Liverpool half of the pitch. Sanchez, who has been barely involved so far, manages to latch onto a pass inside the penalty area, but he's offside and linesman's flag is raised before he can shoot.
