If Casillas joins Porto, it'll be best for him - Carvajal

The Real Madrid defender has backed his captain's potential switch to Portugal but says the team cannot envisage Sergio Ramos leaving

Dani Carvajal believes Iker Casillas will be making the right decision if he joins Porto from Real Madrid.

The Portuguese giants have made a move to tempt the Spain captain to leave Santiago Bernabeu this summer after more than 15 years with the senior Madrid side, with los Blancos' pursuit of David de Gea placing his future in further doubt.

And team-mate Carvajal has backed the World Cup-winning keeper to consider pastures new after a turbulent 18 months in the Spanish capital, in which a number of fans have turned against him following some high-profile errors and a falling-out with former boss Jose Mourinho.

"I repeat: I don't need to get into that topic. I think it's something you'd have to ask him," Carvajal told AS.

"I have an exceptional relationship with Casillas, and if he's made that decision, I think it will be the best for him."

Fellow defender Sergio Ramos continues to be linked with Manchester United but Carvajal insists it is hard to imagine the 29-year-old leaving.

"All I know is that he's our team-mate and nobody imagines him in another shirt," he said of the former Sevilla man.
