It wasn't long ago that Iker Casillas was one of the best goalkeepers in the world. Flying high with Real Madrid and Spain, Iker's won every trophy there is to throw on a Wikipedia page. However, as John Thorn once said, "The heroes of our youth grow old - 'the boys of summer in their ruin,'" and Iker Casillas is no better reminder of that fact. San Iker got old. And he got old fast.

After his ignominious departure from the Estadio Santiago Bernabeu in 2015 with rumors swirling that club president Florentino Perez orchestrated his exit, Casillas signed a two-year deal with Portuguese giants FC Porto, making his debut on August 15th, 2015. Despite overtaking countryman Xavi to now hold the record for most appearances in UEFA Champions League history, Casillas' tenure at Porto has been anything but a relaxing golden parachute to retirement. Criticized roundly for a number of high-profile mistakes in a Dragao shirt, Opta revealed the 34-year-old Spaniard has the worst ratio of goals conceded per game of any Porto goalkeeper since they started collecting data on the Portuguese league.

Casillas is officially the worst Porto keeper in the last 15 years, conceding 28 out of the side's 30 goals allowed this season. In Porto's last 42 years, that record of 30 has only been matched or eclipsed twice. That hurts.

One of the game's last true remaining legends, it's been incredibly sad to see Casillas' rapid decline and subsequent treatment at the hands of Real Madrid. Porto was meant to be his swansong, but at this rate, it's more like a nightmare that simply won't end.
