Personally couldn't give a fuck about either. You can't sign every top player around and in situations where players choose other clubs you can only wish them well and move on. The nonsense which has gone on since Hazard in particular signed for Chelsea in terms of people slagging City off for not doing more to sign him is a bit sad. The club and it's owners have earned the right to pull out of any deal they choose to, and equally top players have every right to sign for someone other than City if they so wish.
There's no need to be trying to apportion blame in those situations are making out like the club have made some terrible error.
