The Spaniard has already announced his intention to leave City after 10 years at the club.
Asked if Foden will be the heartbeat of City's team from next season, Guardiola said: "That is our wish.
"Of course David is a legend – the amount of games, the amount of titles, but that is our wish and we believe he [Foden] can do it.
"He can do it, in small spaces he is so good, Phil. He has this incredible quality for the first reception in small spaces – also the box to box, like a typical English player. He will get the minutes he needs at his age right now.
"Always he has a good impact coming from the bench. Some players don't have an impact coming from the bench, always I have that feeling from Phil.
"Against Atalanta we believed he could play an incredible game and he did it. Alongside him are Rodri, [Ilkay] Gundogan, Kevin [De Bruyne] – many players, but I never doubt about him [Foden]. Whether he plays 90 minutes, 20 minutes or not one single minute, the confidence is always there."
