Iker Casillas is one of football's greatest ever goalkeepers - and he insists those between the sticks should not look past the number one part of their job.
Casillas won five LaLiga and three Champions League titles with Real Madrid as well as the 2010 World Cup with Spain, establishing a glittering reputation. But he recognises that the role of a goalkeeper has changed from a shot-stopper to even more.
However, that doesn't always go to plan. When his former club, Real Madrid, took on Liverpool at Anfield on Tuesday, both Thibaut Courtois and Alisson were guilty of errors which led directly to goals.
