He's given us his best years indeed, I've never denied that, nor has he once voiced his concerns about where the club was heading to, when it was really tough some time ago. That's the kind of professional behaviour I'd like to see more often these days, but on the other hand, it's what I'm expecting from any player under contract.
For my liking, and going back to my initial point, I don't need him to say anything if he does indeed leave. I don't buy this "new challenge crap", even if it's coming from as loyal a servant as Sagna appears to be. On the other hand, it's unfair to expect him coming out with "I did it for the money, etc.", hence why I'd rather he kept his mouth shut completely, like he used to ever since 2007.
