Massimiliano Allegri has been reappointed as head coach of AC Milan, returning to the club for a second stint after the dismissal of Sergio Conceicao, who led the team for just six months. Milan's decision follows a disappointing season where the club finished in eighth place, failing to qualify for any European competition, despite winning the Italian Super Cup under Conceicao's management, according to Channel News Asia and Reuters.

In their final match of the season, AC Milan secured a 2-0 victory over Monza, though the game was marred by fan protests against the club's ownership and overall direction. Allegri, who previously guided Milan to a Serie A title during his first tenure, takes over the role with the ambition of restoring the club's competitiveness, according to BBC and Channel News Asia.

Allegri's first term at Milan lasted from June 2010 until January 2014, during which he led the team to the Serie A title in the 2010-11 season, their first since 2004. His successful managerial career continued at Juventus, where he won five league titles and reached two Champions League finals, establishing himself as one of Italy's top coaches. The club has not lifted a Champions League trophy since their last victory in 2007 and has experienced a decline in form, highlighted by their recent eighth-place finish, according to Reuters, BBC, and Channel News Asia.

Following his departure from Juventus after a less successful second stint, Allegri returns to a club in need of revitalization. Notably, before sacking Conceicao, Milan had started the season under Paulo Fonseca and had a tumultuous path, culminating in their failure to progress in European competitions, highlighting the challenges ahead, according to Reuters and BBC.
