No matter how much we demand from Madrid (or anyone else) for him, I think we are always going to be at a disadvantage if we have to sell him. Whether he leaves for £1million or £100million, how on earth do you replace him? Neuer and Courtois? Impossible targets. Lloris, Begovic, Handanovic? Are they as good? Not for me. I'd peg Neuer, Courtois and De Gea as the 3 best around, so it feels like his replacement is likely to be a downgrade.
But I do feel confident he will re-sign and we'll get another few years from him. He seems genuinely happy here, and also seems our #1 muppet. He just seems to want us to sign all his mates, and we've signed a couple, with another one training with us.
The foreseeable future of the club's transfer policy should just be focused on keeping Dave happy. Perhaps Dave is bezzy mates with Koke and Godin...
