Our most recent meeting
The last time Palace and Millwall faced off also came in the FA Cup, with the two sides drawn against one another in at the third-round stage, back in January 2022.
Unlike Saturday's meeting, that tie was played at Millwall's New Den stadium. Despite a partisan home crowd erupting after Benik Afobe put the hosts ahead, eventually Premier League class would shine through.
A lively affair would eventually turn into the Michael Olise show, the France winger spinning the game on its head, almost single-handedly, in only his third start for the Eagles.
