The Hammers won their first match of 2024, with Bowen scoring his first goals since before Christmas, to end a miserable run of eight games without a victory which had prompted more questions about the manager’s future.

Played five, lost five was their sorry Premier League record against Brentford, the only team of the 43 Moyes had faced in the top flight and not previously beaten.

Finally the rot was stopped as Brentford, already plunged deeper into the relegation scrap earlier on Monday following Everton’s points deduction being reduced from 10 to six, suffered another defeat – their 12th in 15 matches since beating West Ham at home in November.

Where this West Ham have been for the past two months is anyone’s guess. They should have led after only three minutes when James Ward-Prowse flicked on Vladimir Coufal’s cross, only for Tomas Soucek to blaze over from six yards out.

But moments later they did go ahead when Ward-Prowse sent Emerson Palmieri down the left wing.

The Italian defender pulled the ball back for Bowen, who took a touch before lashing his shot past Mark Flekken.

Bowen, who had not scored a Premier League goal in seven matches, suddenly had two inside the first seven minutes.

This time Coufal found the England hopeful 10 yards out and he calmly slotted past Flekken to double the lead.

But the Bees were stung into action and responded in the 13th minute through Neal Maupay, who stole in to score his fifth goal in as many starts against the Hammers.

West Ham looked for a third before half-time, but Soucek missed his kick in front of goal, fit-again Lucas Paqueta volleyed wide and a Mohammed Kudus drive was held by Flekken.

It had not been a particularly niggly half, but Maupay, Brentford’s premier wind-up merchant, seemed to say something which riled Hammers coach Kevin Nolan as they came back out of the tunnel, with Bees defender Mathias Jorgensen separating the pair.

Ivan Toney was inches away from an equaliser when he just failed to get a touch to an inviting cross from Keane Lewis-Potter.

Instead, in the 64th minute, Bowen completed his treble – the first by a West Ham player at the London Stadium – with a simple header from Kudus’ cross.

Home keeper Alphonse Areola saved a Frank Onyeka volley down low at his near post before the Hammers grabbed their fourth in style.

Another Kudus cross was headed out to Emerson, 20 yards out, and the full-back launched a rocket past Flekken into the top corner.

Bees substitute Yoane Wissa pulled another back late on and Areola denied Toney in stoppage time as West Ham held on for a win which was almost as impressive as it was unexpected.
