FIFA presidential adviser Zvonimir Boban is returning to AC Milan as its chief football officer.

A member of the club's 'Hall of Fame', he picked up nine trophies (including the UEFA Champions League 1994, UEFA Super Cup 1994 and four Scudetti) in his 251 matches with the Rossoneri and 30 goals in his playing career.

FIFA says Boban, the deputy secretary general with responsibility for soccer issues, is leaving within days.

"I will always be grateful to FIFA President Gianni Infantino for the opportunity he gave me," said Croatian Boban, who helped his nation reach the 1998 World Cup semifinals.

Milan finished sixth in Serie A this season, extending its failure to qualify for the Champions League to six years.

UEFA is investigating Milan's finances and has threatened the club with a one-season ban from European competitions if it fails to meet targets by June 2021.
