Not quite, if you look at some of the comments on this thread, a lot of it is OTT nonsense such as Mane being as bad as Mayuka or even Ali Dia and that he "isn't a footballer".
And as for Koeman supposedly "calling it" in tandem with the fans, again, utter nonsense. He's clearly been a big fan of Mane since he arrived. He left him out of one game and people were questioning why he was playing him again.
The knee jerk hyperbole about the lad is just plain idiocy.
