Kevin-Prince Boateng rates Brighton manager Roberto de Zerbi ahead of Manchester City boss Pep Guardiola.
Boateng played for De Zerbi at Sassuolo.
He told TVPlay: "If I had had De Zerbi ten or twelve years ago, football would have been different. I think he will be the best coach in the next 20-30 years. He has been able to improve every single player he has worked with, from the reserve goalkeeper to the striker.
"I worked with him when I was 32 years old and I felt stronger than ever. De Zerbi makes you feel really involved, he knew how to cuddle with me when I needed it, to motivate me when I needed it. He really looks for the human relationship aspect of leadership and that is fundamental.
"Is De Zerbi better than Guardiola? I say yes."
