Valencia goalkeeper Diego Alves tore his ACL during the last Liga BBVA match of the season against Almería. The Brazilian keeper is the undisputed starter in Valencia but he will be out until October or even November, with Valencia playing for a spot in the Champions League in August.
That's why Peter Lim's club want to sign a goalkeeper who carries them through the first few months of the season, at least until Alves gets back. Nobody knows how the Brazilian keeper will recover from his knee injury, so it would make sense to have a quality player ready to step it up. That's where Keylor Navas comes in, according to AS. Valencia want him on loan.
Navas has offers to leave Real Madrid but his future is on Iker Casillas' hands. If the captain finally leaves the club, the Costa Rican will stay and fight for a spot with David De Gea. If Casillas decides to stay no matter what, Los Blancos will likely get rid of Navas. It would make sense to send him on loan until Casillas finally leaves, because Navas is indeed a useful goalkeeper.
