Raheem Sterling seems desperate to force a move away from Anfield.
Sterling has been the centre of much speculation during the summer as it looks more and more likely that he will be on his way out of the club this summer, with Manchester City having had two bids rejected, with the Reds valuing Sterling at around £50 million with two years remaining on his contract.
According to the Guardian's report, the club haven't commented on the player's absence from training and will verify Sterling's health as part of its standard procedure.
The 20-year-old has reportedly asked not to be part of the pre-season tour to the Far East and Australia in order to force a move away from the club.
Under Rodgers, Sterling has managed to flourish and become a full England international, and was a big player in the club's title challenge in 2013/14 - and there have been many figures suggesting he is at the best place to continue his development under a manager like the current Reds' boss.
If you are a Liverpool it's hard not to put two and two together and suggest that both are linked and that Sterling is really trying his best to force through a move.
It makes a change from this quote in the Mirror in 2014, where Sterling said of Rodgers: "It's great to have a manager who believes in you; as a young player that is what you cry out for. I'm grateful."
These seem to be the latest in a lot of reasons to leave the club. Some say he has been unhappy at the contract on the table, now he wants to move elsewhere to win trophies, while the alleged behaviour of his agent Aidy Ward has not helped proceedings.
But the Sky report says it is not about money or the club itself, but now the manager - which is something of a U-turn in what has been a prolonged saga. The wounds are clearly open between Sterling and Liverpool, and they don't look as if they're about to heal in the near future as he tries to force his way out of the exit door.
