The Spaniard is still weighing his options and has yet to make a definitive decision, but there is a growing sense that he may be leaning towards leaving England.
According to The Athletic, Xabi Alonso, of Bayer Leverkusen, and Sporting CP's Ruben Amorim are the two managers City want the most.
They believe that both have a style that is similar to what Guardiola has nurtured at City.
City have just appointed Hugo Viana as their new sporting director, who worked with Amorim at international level and at Braga.
