Crystal Palace eased into the FA Cup fifth round with a straightforward victory over League Two Hartlepool at Selhurst Park.
Marc Guehi tapped in from Michael Olise's cross to give Patrick Vieira's side the lead.
Olise then turned goalscorer to double the hosts' advantage from Conor Gallagher's pass.
The game was halted early in the second half due to a medical emergency in the Hartlepool end.
There was no shortage of effort from Graeme Lee's side but they rarely looked like causing an upset as Palace dominated from start to finish.
The Eagles perhaps should have won by a more handsome margin but were wasteful after going 2-0 up.
