Of all the players facing each other over the course of this season's Champions League, there can be few whose careers have seen a greater contrast than the two goalkeepers on show in Portugal on Wednesday night.
Iker Casillas is a legend of the game, decorated at club and international level with both individual awards and all of the biggest trophies.
His opposite number, Ben Hamer, was making his first ever Champions League appearance, and indeed his only first-team start of the season so far, having had a career which has seen him earn more loan spells than trophies.
