I guess he looked at how Zaha's big-money big-club move happened, how it failed and he had to come back with his tail between his legs. That could put a lot of people off and dampen their ambitions.
I'm surprised you think he'd only sit on the bench at Chelsea though. Don't you rate him?
It sounds like he had a £35m release fee when he first signed but it's unclear whether that has been subsequently upped.
If it hasn't, then the price won't be stupid at all. Wouldn't that be a shame?
