Sane has overcome a difficult start to the season to return to the form that won him the PFA Young Player of the Year award last term.
City are in talks with Sane over a lucrative new contract and Guardiola is confident he will follow in the footsteps of the likes of Raheem Sterling, Kevin De Bruyne, Ederson and Sergio Aguero by staying on.
“I don't have any info about there being trouble with Leroy, the last info I had was that it [the contract talks] is going well but the process is not one day – Raheem Sterling [and his new deal], it was not one day,” the City manager said ahead of Tuesday’s visit to Watford. “Except Kevin De Bruyne, it was in one or two days done, the other ones sometimes take longer but hopefully he can stay here for many, many years.”
Sane’s attitude was questioned earlier in the season, with Guardiola dropping the player from his squad against Newcastle in September and Germany team-mate, Toni Kroos, suggesting the City winger’s body language sometimes makes it look like he doesn’t care if he wins or loses.
But Sane has now scored six goals in his past nine games for club and country and banished any talk about his attitude. Sane’s partner, Candice Brook, gave birth to their baby daughter, Rio Stella, in September and Guardiola believes it has been a factor behind his upturn. As with Sterling, he also believes the best is still to come from Sane.
“I'm pretty sure becoming a father helps in many senses,” Guardiola said. “I think he played incredible last season. But I don't like to say too many times to the players how good they are in this moment because the season is too long.
“There are many games to play and it's the same as Raheem, I have a feeling he can do better. In many things he can do better, but with the age he has and the potential he has, we are delighted to have him here and the way he is playing lately.”
