Roger Federer, 20-time Grand Slam singles champion, said in Buenos Aires on Monday that, as long as he feels good, he sees “no reason to stop” his career.

Alexander Zverev, who will face Federer in five exhibition matches, stated he wants to win his first Grand Slam before the likes of Federer, Rafael Nadal and Novak Djokovic retire from the sport.

Federer and Zverev will play their first exhibition match in Chile on Tuesday, before they immediately head back to Buenos Aires to play at Parque Roca Stadium.

A day’s break on Thursday then follows before further matches in Colombia, Mexico and Ecuador.
