The 2006 World Cup final featured one of the most dramatic moments in football history.Zinedine Zidane, who had put France 1-0 up with an audacious early Panenka penalty, was sent off in extra time for headbutting Italy defender Marco Materazzi.Watching from the stands at Berlin’s Olympic Stadium was Zidane’s eight-year-old son Luca. He had attended all of France’s games throughout the tournament and was distraught at the end when Italy took the trophy in a penalty shootout — even if he now brushes off that unforgettable match, and his father’s role in it, by saying: “What happened happened. Football is like that.”Two decades later, Luca Zidane is about to play in a World Cup himself. Born in France, and having lived most of his life in Spain, where he is goalkeeper for second division side Granada, he chose last autumn to represent Algeria, where his paternal grandparents were born.“We’ve lived in an Algerian culture since we were small,” he says. “It’s an honour to play for Algeria. The final decision was mine, but I spoke with my family, my parents, my brothers, my grandfather. My father was happy, he knew it was something I wanted to do. To be able to play in a World Cup is a dream for any kid.”Zidane, 28, made his international debut in October, then played at the Africa Cup of Nations, where Algeria lost in the quarter-finals against Nigeria on January 10.On Tuesday in Kansas City (8pm CT, 2am on Wednesday in the UK), he will be his side’s last line of defence against Lionel Messi and defending World Cup champions Argentina.“Messi is one of the greatest players in history,” he says. “But Algeria is a big football nation. We can surprise people. And we have our own threats: (Riyad) Mahrez is a great player too.”The Zidane family home has been the Spanish capital of Madrid since 2001, the year Zinedine became a Bernabeu galactico when signing from Juventus. All four children — Enzo (born in 1995), Luca (1998), Theo (2002) and Elyaz (2005) — followed their father’s footsteps almost as soon as they could walk.“Ever since we were very small we’d all go to (Real Madrid’s) Valdebebas (academy) to train,” Luca Zidane says. “We’d also play the whole day at home: two against two in the garden. “There’d be some rows too, we’re all competitive. My mum used to get a bit tired of it, but they’re really good memories.”The only family member to play in goal, he progressed through Madrid’s youth ranks and was first choice as the under-18 team reached the semi-finals of the 2015-16 UEFA Youth League.His father was then Madrid’s head coach, and in the following seasons Luca was often called to train with the senior side along with Cristiano Ronaldo, Luka Modric and Karim Benzema.Luca and Zinedine Zidane in Real Madrid training in May 2018 (Gabriel Bouys/AFP via Getty Images)“At home he’s your father, but when you go to Valdebebas he’s just the coach,” Zidane says.“He could be a bit harder on you than on the other players, but it didn’t bother me. At that age, whoever is your coach, you have to work hard every day to get to the highest level possible.”
