The local paper here in Chester already has the teams for the game and Parry isn't in it, so looks like you were right!!
I can absolutely assure you it is pure guesswork. Newspapers do it all the time. Every Saturday, the Daily Mail devote two pages to team news and line-ups for all the Premier League games (or certainly used to - haven't read it for a while), and though the injury updates may be accurate, the supposed starting line-ups are all down to the individual reporter's best guess. I am 100 per cent certain the Chester Chronicle do not know our team selection and 99.9 per cent sure they don't even know their own team's. Should they have got either team right, it will have been down to a good/lucky guess.
