Mikel Arteta has backed Bukayo Saka to step up and take Arsenal's next penalty after the winger missed a crucial spot-kick in Sunday's draw at West Ham.
Saka had the chance to put Arsenal 3-1 up seven minutes into the second half, following Michail Antonio's handball, only to miss his first spot-kick since the Euro 2020 final with England.
Two minutes later, West Ham completed their comeback from 2-0 down, with Jarrod Bowen earning a point for David Moyes' side.
Saka's could prove a pivotal miss in the race for the title, with Arsenal now only four points clear of Manchester City having played a game more.
