I didn't say he was taking drugs, I said he was in a video which also included drugs, which I can't imagine pleased Pep or the owners.
As for the for sale bit, obviously it was in the press, several papers as well, but yes, until we set up a Loot section on the OS with a picture of him and Bony on it, we won't actually know he's for sale.
The only reason Nasri will be here the rest of the season is that no one else wants him. Turning up fat after a summer off and basically missing all last season through injury sums up his attitude and whilst Pellegrini may have let it pass, there's no way Pep will. Maybe dropping him from the CL squad was a shot across his now's, but I suspect it was more a torpedo.
But feel free to put a positive spin on every negative bit of press/info about him.
