The Teirney stuff is bizarre and lacking in any self awareness. He's a decent player, with a concerning injury record playing in a secondary European league. To suggest Arsenal aren't good enough for him is deluded. I'm amazed a club the size of Arsenal are even considering buying him. I genuinely thought he'd join a good Championship or smaller EPL side and if he does well there then a move to one of the big English sides might happen. Hutton, who was a better player at that stage in my opinion, struggled at Spurs, it's a big jump from the SPFL to the big English sides. If he leaves Celtic I hope he does well, if he stays I hope his injuries are chronic and he spends next season in the stand. In the end Celtic have him under contract and can play hard ball at this stage of the summer, that might change as the summer goes on.
Sportsound stopped dealing in reality a long time ago, it's fanzine levels of balance these days.
