Varane recently admitted he has "damaged his body" because of repeatedly heading the ball over the years. The centre-back, who said he was on "autopilot" after playing for France at the 2014 World Cup with a concussion, has called for greater protection and better awareness on this matter.
He told L'Equipe: "My seven-year-old son plays football and I advise him not to head the ball. For me, that's essential. Even if it doesn't cause any immediate trauma, we know that in the long term, repeated shocks can have harmful effects. Personally, I don't know if I'll live to be 100, but I do know that I've damaged my body. The dangers of headers need to be taught on all amateur football pitches and to young people."
