After Sunday's dramatic loss to Manchester United at the London Stadium, West Ham got their revenge against the Red Devils as they knock them out of the Carabao Cup with a 1-nil win at Old Trafford.
It was Moyes' first win against Manchester United after eight attempts since he was axed from the managerial role of the club in 2014 and he couldn't have wanted a better venue.
The Hammers travelled north on Wednesday looking for a place in the EFL Cup fourth round and eventually got it via Manuel Lanzini's lone goal.
West Ham got their lead very early on and despite United’s control, they could not get back into the tie – albeit Moyes' men were wasteful too.
Ole Gunnar Solksjaer completely changed the team that sealed the Premier League win against West Ham last weekend, withDean Henderson making his first appearance of the season and Phil Jones was named in United’s matchday squad for the first time in 19 months.
Alphonse Areola and Alex Kral made their West Ham debuts as Moyes made 10 alterations, with Jarrod Bowen the only player to keep his spot.
West Ham started on the front foot at Old Trafford and took just nine minutes to open the scoring.
Ryan Fredericks all too easily ghosted between the returning Alex Telles and Jadon Sancho and cut back for Manuel Lanzini to sweep home.
Despite United's control of possession and the game, Anthony Martial, Donny van de Beek and Alex Telles were presented with scoring opportunities and none of them could hit the bull's eye as the London visitors scrounged up a half-time lead.
Sancho fired right footed over the bar early in the second half after a superb pass into the area from Juan Mata.
And after bringing on board Bruno Fernandes and Mason Greenwood much later in the game, nothing really happened to change the status quo but with 15 minutes to go Sancho burst into the area on the left and saw a curling right-foot shot blocked from close range.
West Ham had a rare chance to seal the win late on but Andriy Yarmolenko hit the foot of the post after going around Henderson. And with United committing men forward Mark Noble found himself one-on-one but fired straight at Henderson.
Pablo Fornals then hoisted a shot high over the bar from the edge of the box as West Ham looked to put the tie to bed. But West Ham hung on to knock out Solskjaer’s men.
