Roger Federer has been challenged to compete for an incredible task by Former World No1 Gustavo Kuerten.
Kuerten has joked he now wants to see the 37-year-old try and add another 900 to his tally before he retires – which is virtually impossible.
“Roger, 100 man, congratulations,” Kuerten said.
“But I want to know one big question, when is going to be the 1000 man? 100 is okay, we know you are able, but 1000, are you able to do it? If you tell me you go for it, I will put my chips on you okay. All the best my friend.”
