The interest has been genuine, there's been to many London based journalists with info on it for it not to be true. Of course when that info crosses the border up here then it becomes exaggerated nonsense.
Arsenal will know all too well about the players injury history and will want reassurances. On the side they will have been negotiating with Tierneys agent about a salary. Makes it quicker for the deal when the clubs eventually come to an agreement.
Now I do not know why Lenny Gaga would know the words "Osteitis Pubis" or why he chose to actually utter that exact medical condition to the press a couple of weeks ago and not just a generic hip/pelvic issue, but right away that phrase would have sent alarm bells ringing on Arsenals side, no wonder they want structured payments based on appearances (if that is the case).
He's had this condition for nearly 9 months. There is already been one reoccurrence when he was forced to miss their cup final after been brought back into their team, and he's not been able to train since.
This type of injury requires complete rest for recovery and he's already shown his body is susceptible to it coming back.
This is in no way triumphant but if he does have recurring Osteitis Pubis then there is the very real chance his career at top level football could be over. A quick google shows although manageable in life, it will end an athletes careers at the top when chronic and frequent.
Makes Celtic actually telling the world about it a tad intriguing.
