Iv'e undergone the toughest moments in my life because of sports events lately. Sport is great, but when the results of your favourite team are bad you feel helpless and want to cry about it.

This is what I felt when I witnessed the Argentina squad and coach doing nothing but disappointing us: what a shame!

I can’t stand seeing the Brazilians making jokes and having fun at Argentina's expense—it’s a part of the game, I guess, but people don’t need to be so heavy on doing this because Argentina is only a rival, not an enemy.

Anyway, this matter is closed, and Argentina still has a chance to qualify, so it’s not worth crying over spilt milk.

However, in these hard and sad moments, there was a game on the air...a sport event by excellence: The exciting US Open.

From the beginning of the tournament I put my eyes on Juan Martin del Potro's games. Honestly, every day I was so happy to see the young talent advancing slowly but effectively. Each passing day was a battle for our boy.

To my great surprise, he was growing each day more professional and confident. However, after seeing the soccer team failing and failing it, was unbelievable to watch the young player turning into a dangerous opponent for his rivals.

I watched all his matches against different great rivals, and, believe me, I thoroughly and proudly enjoyed seeing him assert his dominance over great players of worldwide renown.

His great challenge against Rafael Nadal led him to win more confidence and to fortify his will as well. After this great victory, Juan M, the so-called "la torre de Tandil,” had secured a valuable place in the US Open finals.

The task seemed almost impossible. Why? Defeating Roger Federer is simply as big a challenge as climbing a mountain. Federer is the king of tennis...del Potro is just a young talent with exceptional play.

Strength and resistance were the key words—it’s time or need to step back...

This fortunately ended well for our champion. He never lost concentration, and he never lost hope or will. On the contrary, each time he grew more and more efficient and started threatening even the great Federer.

We have always heard that in life everything is possible—that is very true in the case of Juan Martin. He won because he was blessed to think and believe that he was doing his best.

He won simply because he wasn’t intimidated by the great monster of tennis...so that’s the wonderful achievement for a 20-year-old young man who showed clearly we can win, even against the best of the best.

So thank you so much, Martin, for bringing back the great hope and joy to Argentina.

Thanks for the great bravery and solid determination and for the beautiful and fair play.

We love you so much.
