A cup final often does not offer a player a second chance to redeem himself. The chances are slimmer if you happen to be the man with the gloves.
Liverpool had to pay a hefty price for Loris Karius' debacle in a UEFA Champions League final against Real Madrid whereas his compatriot Oliver Kahn had to surrender the biggest prize in football to Brazil for a blunder in the World Cup final in 2002.
A shot-stopper can ill-afford to lose his focus as all the hard work put in can be undone in a moment of fallacy.
