As a tennis player, I’m definitely on the older side and I have to get used to it to be quite honest.”The 20-time Grand Slam champion says recalling the rush he felt as a young player facing top-ranked champions like Pete Sampras, Andre Agassi and Carlos Moya, infuses him with a fresher mindset facing NextGen stars.“Also playing the next generation of players that’s coming up, it’s just a different feel,” Federer said. “Because you have to imagine when I came on the tour, back in 2002 when I came to Shanghai, I’m playing with the likes of Agassi and sharing the locker room with Carlos Moya, Tim Henman and Pete Sampras. And those are the guys I knew from TV, right?“And then all of a sudden well now the players know me from TV and they’re playing against me. So you have to switch your mind around a little bit and appreciate that, that the young generation is knocking on the door and is really excited to play against you.”
