Monaco will win against Radek, no chance for him, IMO. Caly, 5 sets - he is too old to beat such a consistent player with crowd behind his opponent.
For me it looks like Argentina takes twp points against Stepanek, Czech Rep. takes doubles. Both Delpo and Monaco have their chances with Tomas, so I would put my money on argies.
Only if Delpo isn`t able to play full matches Nalby won`t have a chance to realize his dream in two monthes.
