It's only 1 game into the season, so far too early to judge the success of Paterson and Walsh as signings. Walsh being injured already is not a good sign, but fingers crossed for the rest of the season, while Paterson has certainly started well.
We're not happy about our transfer situation, but I'd be furious if I was a Bristol City fan. Pearson has let these two relatively young players go, plus Famara Diedhiou who was their top scorer and focal point in attack. Also the talented Henri Lansbury went to Luton.
I wouldn't be happy about releasing those players and signing Matty James, Andy King and Danny Simpson. All probably past their best and not adding any long-term value either.
