Crystal Palace may be on a club record unbeaten run, but Everton have proven to be a bogey side of late to the Eagles. BBC Sport explores some of the key themes before Sunday's match.
With victory over Dynamo Kyiv on Thursday, Crystal Palace surpassed a club record that had stood since 1969, with their unbeaten run now at a remarkable 19 matches.
They now put that on the line against an opponent that has proven to be a real nemesis of late. The Eagles are without a win in nine against Everton, have recorded just one victory in 21 league matches versus the Toffees and their last top-flight away victory against them came in 2014.
If they do avoid defeat against David Moyes' side, they would set another outright club record of 13 top-flight matches without a loss, beating the previous mark set back in 1990.
They also are on the longest unbeaten streak of any club in Europe's top five leagues. These really are halcyon days for Oliver Glasner's FA Cup winners.
