Real Madrid goalkeeper Keylor Navas could be forced to miss the El Clasico against Barcelona.

The Costa Rica international is battling a leg injury and is yet to rejoin teammates in training.

With five days to go before the El Clasico, Real coach Rafa Benitez fears Navas won't make it, says Sport.

Navas missed the clash at Sevilla last week, where deputy Kiko Casilla concedes three goals in the 3-2 defeat.

A positive for Benitez yesterday was the return of Marcelo to training. Like Navas, Marcelo also missed the Sevilla clash.
