I heard this, but what I heard in response was that this bid wasn't recent, but some time ago. It's just come out in the news today because the Sevilla president confirmed that they had turned down a bid from West Ham - he didn't say when though. Apparently AC has agreed to move to West Ham in principle and will complete it in the next week when he gets back, so hopefully that goes without any hitches, because the sooner he's gone, the better.
