I know both cities very well and I wouldn’t class Manchester as the beacon many suggest it is. But also, something other than hearsay about him?
A few ideas:
The city centre has been taken over by students and property investors making money from students none of whom pay any council tax.
There is no direct transport link from town to the airport.
Failed developments all over the place.
Failed to get the commonwealth games.
Failed to get channel 4.
Appears in local press only when he is directly and personally affected by something.
Embarrasses himself and the city on social media.
High profile members of his council team being arrested.
His using tax payers money and council legal team for a private legal case.
Strange goings on regarding planning permission for the roof extension on the shankly hotel.
Putting political and football allegiances aside, I don't see any evidence of him having any business savvy.
