Both sides emerged 1-0 victors from their third-round affairs, as the Irons sneaked past Lincoln City, while Mikel Arteta's troops narrowly overcame Brentford.

David Moyes's troops made hard work of their third-round contest with Lincoln City, only sinking their third-tier foes courtesy of a Tomas Soucek winner with 20 minutes left to play, but the hosts' eye-catching start to the campaign is now a thing of the past amid a four-game winless run.

A 2-2 draw with Newcastle United was respectable, but a 4-1 Aston Villa humbling, 2-1 Europa League beating at the hands of Olympiacos and 1-0 home loss to Everton - who defended with vigour and stole all three points with a Dominic Calvert-Lewin strike - have set off a few alarm bells.

As well as going five games in all competitions without a clean sheet, West Ham's failure to make the net bulge against Everton marked the first time in 2023 that the Hammers had drawn a blank in a home match, having previously breached the opposition backline in 18 straight contests at the London Stadium.
