Juventus boss Massimiliano Allegri denies clashing with Andrea Pirlo when they were together at AC Milan.
The pair won the Double with Juve last season.
"I never had any arguments with Pirlo," Allegri told La Repubblica. “The transfer to Juve revitalised him psychologically and change can be cathartic.
“That season, my third on the Rossoneri bench, Milan no longer had Alessandro Nesta, Gennaro Gattuso, Zlatan Ibrahimovic and Thiago Silva.
“It would've been tough for Andrea to do well in that squad too."
