Former AC Milan youth coach Jose Riga has succeeded Chris Powell as manager of Charlton Athletic, the struggling English second-tier club announced on Tuesday.
Riga, 56, took a training session with the first team on Tuesday, just hours after Powell had been relieved of his duties by the club's Belgian owner Roland Duchatelet.
"Jose Riga has been appointed as head coach of Charlton Athletic, the club confirmed on Tuesday afternoon," read a statement on the club website.
"The Belgian-born former Standard Liege boss will take charge of his first game on Wednesday against Huddersfield Town at The Valley."
Riga made his name as a coach in his homeland before joining Milan's technical staff last October.
Charlton are currently bottom of the Championship, albeit with at least three games in hand on all of the teams immediately above them, and were knocked out of the FA Cup by third-tier Sheffield United on Sunday.
Earlier, Duchatelet paid tribute to Powell, saying: "I would like to thank Chris for his commitment and hard work over the past three years. The club enjoyed a number of good times under his leadership.
"However, given the club's position in the league and the number of important fixtures upcoming, I felt this difficult decision was unavoidable at this time."
A former Charlton player, Powell took over at The Valley in January 2011 and led the club to the League One title in his first season before orchestrating a ninth-place finish in the Championship last term.
