West Ham cruised into the FA Cup fifth round with a routine 4-0 home win over Doncaster.
First-half goals from Pablo Fornals and Andriy Yarmolenko put David Moyes' side in control and after Andy Butler put through his own net, debutant Oladapo Afolayan added the cherry on top with a late fourth.
The win sets up a last-16 meeting with one of Manchester United or Liverpool for the Hammers, who have now won their last five matches.
Moyes made eight changes from the victory against West Brom with midweek matchwinner Michail Antonio and the only forward at the club one of several to drop to the bench.
Doncaster had won seven of their previous eight games and boss Darren Moore picked a strong XI, but they had no answer to the hosts' firepower.
