Real Madrid fired coach Rafa Benitez after only seven months on Monday and replaced him with former star player Zinedine Zidane. The three-time FIFA World Player of the Year faces a tough challenge to drag the Spanish club out of its current crisis and back to the heights of success, and prove his ability as a coach. Just hours after the announcement of his nomination, the 43-year-old oversaw his first training session with the club at the small Alfredo Di Stefano stadium in Madrid, walking out onto the pitch to the cheers of some 5,000 supporters."Zizou, Zizou!" they shouted as he entered, wearing a grey tracksuit and fluorescent shoes. The Frenchman gathered players around him. Then he kicked the ball to start a training exercise, drawing shouts of "hurray."Zidane replaces Rafael Benitez, who struggled to win over both Madrid's fans and their superstars during his seven months at the helm. The club has suffered a year-long slump that has seen it burn through two Champions League-winning coaches, see eternal rivals Barcelona win the treble and suffer the embarrassment of several off-field scandals. Zidane has his work cut out, with Spain's many sports dailies pointing to his lack of coaching experience."The Frenchman is a football legend and a great figure of Madrid," wrote the Marca sports daily - Spain's most read."But his coaching experience is inversely proportional to his excellent footballer's experience - limited... and controversial."So far, this experience has been limited to a season-and-a-half in charge of Madrid's feeder team Castilla, which failed to secure promotion from Spanish football's third tier last season.But he has the advantage of knowing the players well - he was the deputy of Carlo Ancelotti, who coached Real Madrid in 2013 and 2014. And the team appeared relaxed yesterday, with players all smiles. The morning's tranquility, however, is but a prelude to the global media attention that Zidane's afternoon press conference at the mythical Santiago Bernabeu stadium will attract.Five facts about Zinedine Zidane- Raised in a tough Marseille suburb, Zidane rose to prominence with Bordeaux, winning the Ligue 1 Player of the Year title in 1996 before big-money moves to Italian giants Juventus (1996) and a world-record 150 billion lira (about $80 million) transfer to Real Madrid in 2001.- "Zizou" assumed global superstar status after the 1998 World Cup, where he bounced back from a red card in a group match against Saudi Arabia to score two headed goals as France beat favorites Brazil 3-0 in the final at the Stade de France.- In his first season at Madrid, Zidane wrote himself into club folklore with a stunning match-winning volley in the 2002 Champions League final against Bayer Leverkusen in Glasgow. A year later, after helping Real win La Liga, he was named FIFA World Player of the Year for an unprecedented third time, a feat only subsequently matched by Cristiano Ronaldo and Lionel Messi.- His career ended in infamy at the 2006 World Cup when, after having scored an audacious chipped penalty off the crossbar after just seven minutes of the final in Berlin, he headbutted Italy's Marco Materazzi in extra time and received a red card. France went on to lose 5-3 on penalties. Zidane claimed that no-nonsense defender Materazzi had insulted his sister and that the Frenchman would "rather die than apologize."- Real Madrid president Florentino Perez appointed Zidane as an adviser in 2009 and the club's sporting director in 2011. In 2013-14 he was assistant coach to Carlo Ancelotti as the club won the Champions League. Soon after, Perez appointed him coach to the club's B team, Real Madrid Castilla, despite lacking the necessary coaching badges. Zidane has since obtained them.
