Gabriel will formally join City in January from Palmeiras.
And he revealed to Extra Time: "It was a complicated decision, but what eventually prevailed was my desire to learn. The presence of a coach like (Pep) Guardiola was decisive as was the size of a club like City. The call and the conversation with Guardiola was also decisive, I'm glad to be working with him."
"But I cheer for Milan (laughs). No, as I said before, I weighed the Guardiola factor. I received advice from people who have worked with him and from others who have played with other clubs interested in my purchase, I evaluated and then selected City."
