That seems to be what Sergio is saying though, Pep has said that numerous times to the media but it sounds like he hasn't said it to Aguero off camera though; if those quotes are accurate that is.Pep has said a few times he wants him to stay and/or sergio decides when he leaves,seems the club are not formally talking to any of them till the end of the season
Pep almost always says he wants to keep players, even if he then goes on to get rid - as he should.
Got to assume the club & Pep aren't stupid though, Pep has given Aguero a challenge, and he is rising to it, and he'll be rewarded for it.
