|11/5||Milan are 11/5 with Betway to beat Atletico on Wednesday
Seedorf played under Ancelotti during his time at San Siro and the Italian says his old charge has been in touch over how to best the capital club.
"He's a partner and a friend," Ancelotti told the Corriere dello Sport.
"It was inevitable that he'd request information. He knows how to deal with it. He's completely into his role. He has great ideas.
"Atletico play in the image of their coach. I remember Simeone as a player. He's smart tactically and gave it all. So his team are like him: strong, compact, with the mentality of a fighter.
"Milan must be careful about the counterattack and set pieces."
