I can see why he celebrated like he did. I dont think he should have done it, but I can understand it. He's been lavished with the "Sixty grand" songs for years and must have been thinking when he began to get doubters that 'they forget the price tag conveniently when it suits', but most of all that it's relaltively recently after coming back from a potentially career-ending leg break and it takes time to get back confidence and whatever form was there before.
All that said, I do believe we need better competition than Kenny is giving him in that position.
