There is a big difference between Ade/RSC and Tevez though isn't there? Their value decreased for different reasons, Tevez has driven his price down by deliberately breaching his contract so not only is there a huge matter of principal at stake but the club may well be in a position to not waive off the money which they almost certainly wouldn't be with the other two. Mind you I'm pretty sure if they thought they could sue Mark Hughes 18m for the RSC deal then they might try.
I realize that they are different situations. I'm just pointing out that regardless of why, players values often decrease. The notion that City are going to sell him for 20 million (or whatever price in January) and then try suing him just seems hugely unbelievable. And to be honest, I imagine that there's enough sensible people behind the scenes at City who will just want rid of him and want to move on to better things as we have done.
Dragging him through the courts, to try and salvage money which we're unlikely to ever see, whilst racking up lawyer's costs, won't be worth it and I imagine the club already know this.
Although I do understand why it can be argued that they could if they so choose, sue him.
