The two former teammates have both returned to the San Siro this season and Kaka has backed his new coach to lead the Rossoneri to success.
"Seedorf was a technically fantastic player and very intelligent," he told TV Globo. "He loved to talk and guide the others on the field, so he had the profile of a coach even when he was playing.
"It's the first time one of my old teammates has become my Coach. It's strange, as the person who was by my side on the pitch is now giving me orders from the touchline.
"He is very disciplined and organised, so he knows what he wants. He learned so much from playing in the biggest clubs in Europe."
Seedorf will take charge of his first game as manager of Milan when they host Hellas Verona at the San Siro this evening.
