Who will take Iker Casillas's record?
Though Pepe Reina is still above him in the rankings ahead of a pending move to AC Milan, it is Cristiano Ronaldo who looks the most likely to catch Iker Casillas.
Unlikely as it is, were Casillas not to appear in Europe at all next season, Ronaldo could feasibly draw level with his former Real Madrid team-mate at the 2019 UEFA Super Cup. That, though, would require him to appear in this year's Super Cup, six UEFA Champions League group stage games and nine UEFA Europa League knockout phase matches next term, plus the 2019 curtain-raiser in Istanbul.
The 150+ club is made up of three goalkeepers, four defenders, three midfielders and two forwards. Aside from Ronaldo, the other striker to feature is Raúl González, himself a long-time talismanic figure at the Santiago Bernabéu whose final campaign in the Spanish capital (2009/10) crossed over with Ronaldo's first.
