The image of a tearful Roger Federer, sitting alongside his great rival Rafael Nadal as he contemplated the final moments of his professional career, went viral in 2022.
It was the end of a career that spanned 24 years, in which the Swiss great claimed 20 Grand Slam singles titles, including an all-time men's record of eight Wimbledon trophies.
He was the first of the 'Big Four' players - Federer, Nadal, Novak Djokovic and Andy Murray - to retire, marking the slow closure of one of the great eras of the game.
In an exclusive interview with BBC Breakfast before the release of a Prime Video documentary about the final 12 days of his career, Federer spoke about retirement, his great rivalries and why he is excited about Euro 2024.
