Firstly he is a player in his prime and he ideally needs regular football 60-90 minutes week in week out to be performing to the best of his ability,
Also given his track record the potential he has is obvious, he'l fit in here and should be one of our best players which will be a confidence boost, if he Is a confidence player which I suspect he is then cardiff will reap the benifits of campbell hitting top form.
I'm going to predict 8-10 goals beetween now and may and about the same in points won from his contribution up front
