De Gea staying Manchester United and Casillas heading for FC Porto, means Real Madrid are moving for another goalkeeping option instead.
Manchester United have firmly drawn their line in the sand regarding the future of goalkeeper David De Gea, having reached a point where they won't accept any bid from Real Madrid, unless they can tie up a favourable deal that would see defender Sergio Ramos head in the opposite direction.
As such, Real Madrid are set to concede defeat in their pursuit of De Gea, at least for this summer, according to popular Cadena SER radio show 'El Larguero'.
Real Madrid president Florentino Perez expected to have a deal secured for De Gea by now, but given Manchester United flatly refuse to negotiate, the sense of urgency to sign a goalkeeper has grown, given the pending departure of Iker Casillas to FC Porto.
The exit strategy for 34-year-old Casillas must still be resolved, given there's a big difference between what FC Porto have offered, and the outstanding salary he's due to cover from Real Madrid.
Nonetheless, with the squad due to report for duty on Thursday evening, the clock is ticking, especially as they're due to journey to Australia to begin their pre-season schedule at the weekend. Keylor Navas is struggling with injury, thus Real Madrid must sign another goalkeeper.
Who will Real Madrid turn to now?
Originally a product of their youth system, when Casilla left for Espanyol in 2007, Real Madrid retained a 50% stake in his economic rights and an option to take him back. As such, it is believed an operation costing Los Blancos around €4 million will be completed for the 28-year-old, without any delays and before the weekend.
Casilla is a very good keeper, although he's certainly not the man fans were expecting to see competing with Keylor Navas for a starting spot in the team, ahead of the 2015-16 season commencing.
However, his form with Espanyol has been consistently high over recent years, earning him calls to the Spain squad, coincidentally, as an alternative option for De Gea and Casillas in the national team plans of Vicente del Bosque.
