David De Gea is still waiting for Real Madrid to make the final approach and show real commitment about a potential transfer. According to ABC, De Gea has declined two different contract extensions because he wants to join Real Madrid, and while Los Blancos are interested in signing him away from Manchester United, they still have to sort Iker Casillas' situation out.
Given that De Gea's contract expires on 2016, it should not be hard to negotiate his transfer, otherwise Manchester United would probably ask for a huge amount of money before letting him go. In fact, it seems that United are preparing themselves for De Gea's departure by signing former Barcelona goalkeeper Víctor Valdés, who is now playing in Manchester United's Reserve side.
Real Madrid will most likely need to make a move soon, as De Gea will definitely want to make his long-term plans as a footballer. And no matter what Casillas thinks about this, it's arguably time for Real Madrid to move on and let the captain walk into the sunset.
