Hammers v Man U : The key talking points of a crucial 2-1 win

The Details

West Ham (0) 2 Summerville 74, Bowen pen 90+2

Man United (0) 1 Casemiro 81

The Hammers made it three home wins in a row against United - thanks to an injury time penalty from Jarrod Bowen.

The signs had been far from promising in a first half dominated by Erik ten Hag's team. Alejandro Garnacho hit the bar and curled just wide. Diogo Dalot blazed over wildly, having nudged the ball past Lukasz Fabianski to give himself an empty net to aim at. A Christian Eriksen corner curled onto the top of the crossbar. The Irons' keeper also did brilliantly to keep out a header from Casemiro just before the break.

But they came good in the end to somehow claim a 2-1 win. Here are the big takeaways:

Lopetegui turning the tide

Having lost three of their opening four home games in the league this season, the pressure was on. Julen Lopetegui couldn't afford a defeat if it also involved a dud display and after 45 minutes, it really wasn't looking good.

But the Spaniard's half-time team talk and triple substitution proved to be inspired. He withdrew two players who had picked up bookings - Tino Mavropanos and an underwhelming Lucas Paqueta, along with Carlos Soler - and their replacements all played their part in a great turnaround.

Crysensio Summerville in particular was dynamite and the ex-Leeds winger was on hand to score the equaliser after fellow sub Danny Ings had got into the danger zone to scuff a shot into his path.

Thomas Soucek also shored up a midfield that had been swamped before the break.

But as well as the personnel changes, it was the raising of the tempo and energy levels which played a key part. For that, Lopetegui deserves great praise. He got a tune out of a side that had been so meek before the interval.

Aaron Wan-Bissaka among those transformed

The former United right back had a troubled first half, with Garnacho giving him a torrid time. We saw a completely different player after the teams turned around. He found a new lease of life and started taking on players, driving forward like a man possessed - as if on a one-man mission to punish his old club for deciding to offload him. He was a revelation.

Michael Antonio's fabulous workrate

Just when you think the old warhorse is a busted flush and not the modern striker the Hammers really need , he comes good again. It was a superb bit of line-leading from the powerful number nine. His pace and strength and willingness to ask questions of his markers gave the Irons hope during that poor first half. Then, for 20 minutes until he was taken off - having run himself into the ground - he stepped up even more. One burst to the byline set up a great chance for Emerson and it was typical of his work.

Increased optimism

The Hammers badly need this to make the London Stadium feel like home again. Defeats to Villa (on the opening weekend of the season), Man City and Chelsea had made it a miserable start to the season and raised immediate questions about the Lopetegui project. This win buys him more time.

They are up to 13th in the table now and have a better foundation to tackle the next month's fixtures. They begin with a trip to in-form Nottingham Forest and travel to Newcastle either side of home games against Everton and Arsenal. Not an easy set of fixtures but wins against United - even when they are not the force of old - will do wonders for confidence.
