Former AC Milan star Andrea Pirlo has no doubts about the potential of Sandro Tonali.
Tonali is leaving Milan for Newcastle in a 80m deal.
"He is very good but he is different from me on the pitch," Pirlo told La Gazzetta dello Sport.
"He has everything to be a champion but he is more a midfielder for a two-man midfield. He could already play for a great team.
"He is the best in this league."
