It's not just what he has posted, if you look at every single twitter account that has started this rumour or claimed to be in the know they're all coincidentally similar, why on earth would a student journo from Hull or Leicester have this news before radio Sheffield or James Shield for example.
It looks to me as though a very sad person or persons have created multiple accounts to get this rumour going and then a couple of the "transfer news" accounts have picked up on it and it's snowballed from there.
Like I've said if I'm wrong I'll hold my hand up and Jags may even sign at some point but Twitter trolls saying it's a done deal are just making stuff up imo.
