Inter Milan boss Roberto Mancini has hailed the influence Andrea Pirlo has had on Juventus's success.
Pirlo quit AC Milan four years ago for Juve and has won the Scudetto every season since.
"[Andrea] Pirlo is one of the best midfielders in Europe over the last 15 years," Mancini said.
"He made the right choice in leaving Milan and moving to Juve. To find players like that would be great, even at 31 or 32 they could still make a difference in a team like ours.
"Sometimes you're lucky enough to get them for nothing [as with Juventus and Pirlo], sometimes you have to pay something."
