City boss Guardiola, who arrived at the club in the same summer as Sane, in 2016, said: “It's a question for Leroy, his agents and the club. I'm not involved in that.
“What's important now is that he has to recover well and after that he knows what we think of him, that we believe in him.
“It's (only) awkward because I cannot see him on the pitch. He's a nice person, I know him quite well. I was the guy who pushed the club and convinced him to come here even though he didn't play regularly for Schalke.
“I have no doubts about him and his quality but what I've said many times is each one has his own family, desires, dreams and, above that, I cannot do anything else.
“Three years ago is different to right now. I'm not the same guy I was when I arrived here and the players are the same.
“They have their dreams and after the dreams are accomplished it needs another thing. I don't know.
“What I want is for him to come back fit. His knee looks really good and after that, honestly, it's not of my business. It's not in my hands.”
