The German also refuted claims his relationship with Guardiola soured towards the end of his time at City.
"Pep and I had a good relationship," Sane told Der Spiegel.
"He raised me to a completely new level. Mainly by working on little things: with which foot do I take the ball in which situation and how? What is the best action to open the space?
"Other coaches tell you that too, but he really did it every day until I did at some point have a little man in my ear with his voice that told me what to do when and how."
