Last year, Emery said of Jackson: “He was starting the pre-season with the Under 21s and when he was progressively coming to train with us, he was showing his potential. We worked during the one year on his skill, he improved his understanding better, how he could exploit his potential. And playing minutes and getting experiences was the next step.But his attitude as well was fantastic. He was always learning. He was always demanding to train more, to be focused. He was also being a professional every day out of training sessions at home because he was focused on football like the first priority of his life."
