One-club men - Five of the best

Iker Casillas (Real Madrid)

There are very few who come out of the Real Madrid youth system and become modern day greats. Iker Casillas is one of them. Known as San Iker or Saint Iker, Casillas came through the ranks at Real Madrid and established himself as the top dog between the sticks in the early nineties. Arguably the greatest goalkeeper of his generation, Casillas has been the only constant in the expensively assembled Real Madrid sides of the last 10 years. From the Galacticos of the Figos, Zidanes and Beckhams, through the Calderon era of Robben and Sneijder to the present day Ronaldos and Kakas, Casillas has seen it all. Branded as a complete goalkeeper due to his ability on the ball, Casillas is the highest capped goalkeeper in Real Madrid history.
