West Ham have never beaten Manchester United by more than a four-goal winning margin.
They have seen off the Red Devils by four on three occasions; the first was back in October 1926, the second was a 5-1 win four years later.
The third came in November 2010, when Avram Grant’s Hammers thumped Sir Alex Ferguson’s side in the League Cup. We’ve relived that game for you here…
A little over two years previously, the two managers were facing off in the final of the Champions League when Grant was in charge of Chelsea.
Going into this quarter-final, Grant was under pressure, with the Hammers bottom of the Premier League.
Former United man Jonathan Spector was on the home side, current West Ham man Javier Hernandez lined up in attack for the visitors.
Forgotten men Bebe and Gabriel Obertan were handed rare starts; which was a boost for West Ham in pursuit of their first League Cup semi-final in 20 years.
Midway through the opening period, Spector stunned his former side. After some smart interplay around the area, Victor Obinna flighted in a delightful in-swinging cross from the left.
Spector beat a static Darren Fletcher to the ball and nodded his diving header into the bottom left-hand corner of the net.
15 minutes later, it was two. Spector did an incredible Scott Parker impression; collecting the ball around halfway and driving forward with hugely impressive close control.
His ball into the front didn’t quite stick, but as Fabio slipped, Spector got maximum reward for following his pass. After taking a touch, he hammered home.
The first half also saw John O’Shea take possibly the worst shot of all time.
As the snow began to tumble, United’s defence crumbled. After Spector’s first half double, it was Carlton Cole’s turn to take centre stage in the second.
The third goal was so simple; Obinna was in acres of space to cross from the left and Cole easily beat Jonny Evans to power his header past Thomas Kuszczak.
It was that Obinna-Cole axis that provided the fourth of the night as well. Obinna was beginning to enjoy himself, embarrassing Rafael before sliding the ball into the box to Cole.
The target man embarrassed Evans by rolling him with ease, before slotting home.
It was by far West Ham’s biggest win over United in the modern era. With the Reds tearing themselves apart, could a repeat be on the cards tomorrow?
