Real Madrid goalkeeper Keylor Navas could be on the move to Porto to replace Iker Casillas.

Casillas is considering retirement after suffering a heart attack a fortnight ago.

Andrea Salas, Keylor's wife is currently on holiday in the Portuguese city visiting a friend and has posted a series of pictures from the trip on her Instagram account.

One is tagged with the message "¡Nos quedamos!" (We're staying here) and has been interpreted by A Bola as a subtle message as to where Kelyor could be playing his football next season.
