"Pep is a very demanding coach and adapting to what he wanted was not easy during the first year," Aguero told Argentine TV channel TYC Sports. "Besides my responsibilities as a striker, he wanted to get me involved as the first defender of the team. When Gabriel Jesus arrived, he had more options and I started to play less.
