West Ham earned a critical late 1-0 win over Swansea City at London stadium.
Diafra Sakho came in from the cold to hit a last-minute winner and dig West Ham manager Slaven Bilic out of a hole.
The London Stadium was almost in open revolt following an insipid 89 minutes from the home side against Swansea.
But Sakho, who if he had got his way on transfer deadline day would now be in France playing for Rennes, climbed off the bench to secure a 1-0 win and bail out his boss.
Bilic admitted West Ham deserved the boos from their own fans during the game.
Bilic said: "It's a great three points, a clean sheet and nobody can say that we didn't deserve it as the game went on.
"You could feel the pressure was on the players. It wasn't good. We deserved to be booed at half-time.
"The fans are demanding, they want the best for the club and we were poor. So we deserved to be booed, definitely."
