Iker Casillas has hailed the influence of £20 million defender Pepe on Real Madrid's success so far this season.

The Spain goalkeeper said: "It's true a lot of people doubted him because of his price-tag. £20 million is a lot of money, but he has done very well to adapt to a new Liga and also with a team which is leaders.

"What's happened to Pepe is the same as what happened with Sergio Ramos, who has also developed into a great player."
