Actually I've just been thinking Grosjean vs. Agassi is NOT a marquee match at all. Agassi would kill Grosjean. I'm pretty sure of it. Grosjean doesn't have the game to hurt Agassi right now on hardcourts.
So the Ferrero/Ferreira would turn out to be a better match I think.
I have to disagree with you here.
Grosjean vs Andre:
1998-08-31 U.S. Open Hardcourt R128 Andre Agassi (USA) 6-4 6-1 6-4
2001-05-28 Roland Garros Clay QF Sebastien Grosjean (FRA) 1-6 6-1 6-1 6-3
2001-11-12 Sydney Indoor Hardcourt RR Sebastien Grosjean (FRA) 6-3 6-4
2002-10-14 Madrid Indoor Hardcourt SF Andre Agassi (USA) 6-4 3-6 6-4
The head to head is tied, with Grosjean having beat Agassi on two different surfaces. Their most recent match, which was not long ago, went the distance.
Grosjean can give Andre a match, and has everytime since they first time they played.
Furthermore, until his magnificant comeback against mantilla, Grosjean had not lost a set.
Also, Andre has not been tested this tournament. Grosjean will provide him with a stern test.
Ferrero vs Ferreira
1999-11-01 Paris Indoor Carpet R64 Juan Carlos Ferrero (ESP) 4-6 6-2 6-2
2001-05-07 Rome Clay QF Juan Carlos Ferrero (ESP) 6-0 6-2
Juan Carlos Ferrero (ESP) leads 2:0
If Ferrero can beat Wayne in 1999 on carpet (I will remind you that Ferrero did nothing indoors untill Paris 2000), I would have to like his chances here.
