Chelsea boss Carlo Ancelotti says he always felt Ronaldinho was in decline while he worked with him at AC Milan.
Ancelotti did tend to leave Dinho on the bench during the last year of his tenure.
"I am not surprised by the decline of Ronaldinho. I saw it coming," Ancelotti told the Corriere della Sera.
"His physical condition has always been precarious, while nobody could doubt his talent.
"I admire the way Allegri very quickly understood the shape of his team. Milan use their heads and will win the Scudetto. I think Allegri is better than me!"
