Nicole is a mess right now. She wouldn't do anything good for the team.
Of course, when she's playing well, it's important to have her on the team because she always deliver but right now, she can be with Radek.
I think the team is going to be Petra, Iveta, Lucie and Kveta.
Nicole wants to focus on ranking again and also doesn't want to lose in FED CUP because she knows she is not playing well, that's smart decision I think she wouldn't be nominated anyway though her win/loss ratio is amazing in FED CUP, especially in singles
I would nominate Benesova, Kvitova, Safarova and Peschke
