There have been incidents like this in the past which have proven to be true, but started as rumour.
The more things keep being proven true the more likely that things like this are true. You also can take in to account his demeanor on the pitch, the way he acts like he doesn't really care and how the management team are seemingly cracking down on it, as well as his response.
All that points to a player who is ill disciplined, with very little drive to change who is costing the club and awful lot of money. It also makes him look like someone who is not fully committed to his role as a professional athlete.
Take off the blinkers.
