Ferrero said his best match ever was the time he beat Agassi at US Open the year he made finals. That was a helluva performance to beat Agassi like that. Almost beating Hewitt in the WTF 6-4 in the fifth, vs. a prime Hewitt, shows just how good JCF was. Unfortunately he didn't have the physicality to stay at that top level for a long time.
Facing Federer book was called "pretty addictive" by Steve Tignor :)
