Who said it's someone special? I don't expect a big name to be quite frank. Rabadzhieva is not an elite player and I'm pretty sure she will stay in Zurich same for Olessya Rykhliuk.
Rabadieva is elite versus who is free right now, seriously injured overrated players or old finished 'stars'. Neither Werblińska nor Havelkova (FF WGP) are stable.
