Interestingly.... And maybe this is just me being over-analytical, but Bishop doesn't actually say that it was his decision not to come to Blackpool in that statement. He does say that he it was his decision to go to Portsmouth, but he's a bit more coy about how that came about ‘I spoke to the manager (Cowley), I was open with him, I said “I’ve got to have these conversations”. And from those conversations I’ve ended at Pompey and am happy with my decision.
So what does "And from those conversations, I've ended at Pompey and I'm happy with my decision" actually mean? It's certainly not the same as saying 'And as a result of those conversations, I decided to choose Pompey' that's for sure. It feels to me like a statement that is crafted to give an impression of one thing, whilst actually not saying that at all.
There's certainly nothing in what he has said there that suggests that Blackpool didn't pull the plug as was originally suggested.
