Imo, unless he has been a disgrace in terms of discipline, Jo has had a very raw deal and has reason to feel agrieved with how he's been treated at City.
I didn't agree with signing him, it was a joke. However, we all know what despot that was down to.
Regardless, whilst he has been poor he has not been any worse than Benjani, Vassell, Caciedo, Evans, etc, all of whom have been given chances at this expense.
To have a 21 year old with a big price tag, in a foriegn country and to take every single opportunity to drop him is not on imo.
I don't rate him as anything special but there are signs he could go on to be a decent top flight player. He needs nurturing though for that to happen.
The man management of him is totally opposite to what a player in that circumstances needs to be a success.
(Of course, if he hs been way out of order, and I dont mean just one trip to a club when he should have been staying in, then I have little sympathy for him)
