Cerundolo: "It's too early to say I'm playing the best tennis of my life".

Francisco Cerundolo plays this Sunday in the final of the ATP 250 Buenos Aires against Joao Fonseca, the sensation of the moment.

The Argentinian has put in a faultless performance to eliminate tournament favorite Alexander Zverev.

In a press conference, he spoke of his form: "I think I've played some excellent tennis at times over the last four years, but it's true that this week I felt very comfortable and played well.

It's a great week for my career. I don't want to say it's the best week of my life, I don't want to get ahead of myself with four matches; it's too early to say I'm playing the best tennis of my life.

I'll show it if I play well for a few months, not just for a week."
