Matteo Berrettini has spoken of how emotional he has been since his «idol», Roger Federer, retired from professional tennis at the Laver Cup. The Italian, who overcame Felix Auger-Aliassime of Team World on Saturday to secure two points for Federer's Team Europe, explained that he «couldn't sleep» because he was so moved by the Swiss superstar's farewell. Ad For Berrettini, it was a hugely significant moment being on the same team as Federer when he bowed out from competitive tennis, and he admitted that he would probably not even be a player himself had it not been for the 41-year-old's impact.
