West Ham eased into the FA Cup fifth round with a comfortable win over League One outfit Doncaster.
Pablo Fornals handed the hosts the perfect start at the London Stadium after coolly slotting home Ryan Fredericks' unerring pullback after just two minutes.
Andriy Yarmolenko doubled West Ham's lead soon after the half hour mark with a cool dink over Ellery Balcombe, following selfless work from Said Benrahma.
And it was three-nil soon after the half-time interval after a bizarre own goal.
Andy Butler looked to thunder the ball clear from the goal line, only for the defender to awkwardly slice into his own net.
