Of course I know that; representatives of the club will first find out if he's interested, then informal discussions will take place between the players reps and the club to see if a mutual agreement can be met before any official bid is lodged officially.
But, May was when Ross Barkley informed Ronald Koeman that he wanted a challenge, and I presume his representatives would have been informed weeks/months prior that he wanted out, so I'd imagine his name would have been brandishing around boardrooms throughout the country.
Now, conservatively, if we say he's been "informally" in discussions with clubs for 4 months and not one as come to an agreement with him, does that not strike you as strange. A fantastic talent, well thought of throughout the game and people think that it's all to save a couple of million in a transfer??
A talent becomes available and top teams jump, even if they don't need him. A purchase that stops a competitor grabbing him. If Spurs are waiting till the end of august to save £5/10m then that says it all, nobody else wants him and Spurs aren't that fussed because they're prepared to wait it out
