Real football fans do not change their allegiance ffs! Real football fans would no more likely swap clubs as they would sell their offspring.
It is perfectly reasonable to understand a City fan supporting a 'pheonix club' if SISU continue with this nonsense over a period of time but no City fan will start supporting Aston Villa, or anybody else.
The true danger is 'new or potential' fans that previously may have ended up at the Ricoh due to Coventry being their local team are much more likely to go to Villa Park than Shitfields.
