He's probably doubled his wages at least and will have a substantial length of contract so will have secured his and his family's future. How could anyone blame him for that? Plus although I feel Chesterfield are third favourites to go up, they've still got a very good shot at it. He could actually make the difference for them.
I thought I saw he had signed an 18 month contract at Chesterfield, so it may not set him up for life, but it will certainly help, and I can't blame him for going.
We did him a favour by signing him when he had certain off-field problems, but he repaid that by signing a longer contract with us meaning we get some compensation, so I will wish him all the best, apart from a certain game in a couple of weeks. His influence of the field of play has been huge, so, yes he just might make the difference for Chesterfield.
Meanwhile, I trust and hope that Phil Parkinson has plans for this likely eventuality.
