To everyone who is afraid of Falla (or has hopes for him) - the guy is 10-17 on grass for his entire ATP career. And at 28, he is no longer young and rising.
And they have met not once, but twice at Wimbledon. In 2004 Federer won 6-1, 6-2, 6-0.
and Fed had harshly defeated Falla in Halle just before their famous tight match, yes.
But Falla isn't that bad on grass : defeated Isner and Mahut in last Wimbledon in a very convincing manner.
For information, Falla's just arrived this week in Europe after winning Bogota challenger on clay against Giraldo last sunday.
Of course Fed is highly favorite but anything can happen
