Seedorf announces retirement, confirms Milan appointment
The former Netherlands international has been heavily linked with the role following the sacking of Massimiliano Allegri on Monday.
Allegri paid the price for a dismal season for Milan, who sit 11th in Serie A after 19 games and were beaten 4-3 by newly promoted Sassuolo on Sunday.
And the 37-year-old, who won two Serie A titles and two UEFA Champions League crowns as a player at Milan, confirmed he is to leave Brazilian side Botafogo and take over at San Siro.
He told a press conference on Tuesday: "I am here to announce that I will retire from playing after 22 years.
"It has been a difficult decision, but I am satisfied with what I have achieved in my career. Here at Botafogo I am happy because I leave the team with qualification to the Copa Libertadores.
"I leave an improved club, especially for their mentality and team spirit.
"I will be the coach at Milan.
"This experience of the last year and a half has made me grow up a lot and will help me in my next step, as coach of Milan, who have hired me in a manner both elegant and correct."
The decision brings to an end an illustrious playing career that saw the midfielder feature for Ajax and Real Madrid in addition to his time in Italy.
Seedorf is the only man to have won the UEFA Champions League at three different clubs (Ajax, Real and Milan), while also winning the Eredivisie on two occasions with Ajax, and La Liga in 1997 while in the Spanish capital.
However, it was at Milan where Seedorf spent the majority of his playing career, leaving in 2012 following a 10-year spell.
Now Seedorf has the task of saving Milan's 2013-14 season, which is in danger of ending in mediocrity.
