West Ham were out-shot eight to one in the first half and had goalkeeper Łukasz Fabiański to thank for keeping them in the game in the opening 45 minutes.
The Hammers were a much more cohesive team in the second half, though, and went in front when Todibo and Guido Rodríguez combined to turn the ball over midway inside Manchester United territory. Seconds later, Summerville had put the Irons in front.
“We had to show way more resilience in the second half,” Kilman continued. “The manager’s message was we just had to make sure we improved on that performance in the first half and we did. We had some really good moments, pressed really high, gained the ball in good areas and it helped that the fans pushed us on really well.
“There are so many top teams in the Premier League so, whoever you play against, you know you’re going to be up against tough, tough opposition. Obviously Manchester United are Manchester United, so it was just great to win.”
Kilman also had no doubt that referee David Coote’s decision to award a late penalty for Matthijs de Ligt’s challenge on Ings, following a visit to the pitchside monitor suggested by VAR Michael Oliver, was the correct one.
“I looked at it back and I thought that was the right decision,” he confirmed. “Of course, that’s the referee’s job, and he had time to look at VAR, so I think he got it right.”
