Real Madrid legend Fernando Hierro has been appointed as assistant first team coach to Carlo Ancelotti, taking on the role vacated by Zinedine Zidane.
In 14 years as a player at the Bernabeu, central defender Hierro won three Champions League trophies and five La Liga titles.
The return of the 46-year-old after 11 years away was announced in a club statement which confirmed that he would take the role left vacant when Zidane took charge of Madrid's Castilla B side earlier in the summer.
"Real Madrid would like to announce the addition of Fernando Hierro to the coaching staff as the first team assistant coach in replacement of Zinedine Zidane," the statement read.
The appointment was immediately welcomed by Ancelotti, with the Italian head coach tweeting "Welcome Fernando" from his personal account.
Englishman Paul Clement, linked with the manager's job at West Bromwich Albion earlier this summer, remains part of the coaching staff and usually takes charge of tactical training sessions.
Hierro's role is expected to be similar to that of Zidane last season, passing on advice in one-to-one sessions with individual players.
The appointment was something of a surprise given that Hierro had reportedly had a cool relationship with Madrid president Florentino Perez following his unexpected exit from the Bernabeu as a player in 2003.
He then spent a season in Qatar with Al-Rayyan before playing for Bolton Wanderers in the Premier League. After retirement, he had a directorial role at the Spanish FA and was sporting director at Malaga before leaving in 2013 after a clash with the owners.
