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.
As I mentioned in my earlier post, Monaco and Radek played the 5th rubber also three years ago. That was on carpet in Czech rep. Monaco had had a 5-set loss to Berdy in 1st rubber. He didn't play in doubles whereas Radek had only played in 3-set doubles win. That Steps-Monaco match ended in Radek's 3-set win. I don't know why Monaco played that badly against Stepanek, despite taking match against Berdych 'til the 5th set. I'm quite sure that already in '09 Berdy was more difficult player to beat on carpet than Steps, maybe Monaco was tired. Or he was too nervous. I would rest Steps against DelPo, and put him playing against Monaco for reasons above unless Rosol impresses against DelPo.
