Roger Federer keeps promise to young fan from 2017 US Open press conference

Just incredibly heartwarming, this

Tennis icon Roger Federer provided a young fan with 'the best day of his life' after the pair shared the tennis court, five years after the youngster initially challenged him to a match. Back in August 2017, Izyan 'Zizou' Ahmad was offered the chance to ask Federer a question as part of the #NetGenerationKidcaster event. Speaking at a press conference ahead of the US Open tournament in New York, Ahmad plucked up the courage to ask the former world number one a question https://twitter.com/TansuYegen/status/1556950415647940609 He asked: "You have been the most consistent player of all time. Can you please continue to play for eight, nine years so that I can play you when I go pro?" However, 'Zizou' wasn't done there, and he wanted some assurances - so he challenged Federer further. "Is that a promise?” he asked, before Federer responded: "Almost. Pinky promise." Now, five years later, Federer did exactly what he said he was going to do. Ahmad was invited to Zurich, Switzerland, alongside his coach for what he believed was going to be a training session. The pair sat down in a local cafe, with Ahmad completely unaware that he was being secretly filmed by Barilla. He then got the chance to face off against Federer on the court.
