Abreu was teammates with Guardiola at Dorados de Sinaloa, where Lillo was head coach.
He recalled, "When I got to Dorados, Pep and Lillo began to tell me that I was wasting seconds. They inflated my b***s with that, and I, who am capricious, reluctant, stubborn, and also, I scored goals, I thought ... 'these two screw me saying that I'm losing seconds'. Until at one point I took off that helmet, that of being a person who did not understand who was talking to me, of seeing that they had a path, a much better and greater learning, and I began to listen to them.
"I began to understand that there was a lot of coherence in what they told me, in giving continuity to the game, the positioning, the profiles, the oriented control, admitting that I was going to grow much more as a striker, and as a footballer.
"That the play was going to have a greater chance of completion for me, the team, and that's where we started."
