I had to look up in Google to find who this guy was. The Overture wasn't really beaming with his name.
Anyway, he is a Czech soccer player past his prime.
1. When did you register this domain? Like a few days ago. I've also checked Alexa and there seems not to be any prior records. So, did you ever asked yourself why was this domain available despite this guy playing 8 years of International soccer for your country? I'll tell you why - because of lack of interest.
2. Tell you the truth I know of several domains with some popular or widely acclaimed European soccer players (usually past their prime
that are not registered. If I was you I wouldn't be overly enthusiastic about the prospect of this one either.
3. Even Robert Pires domain just couldn't ever sell

4. Most of these soccer players (not counting those image craving self-narcistic metrosexuals like David Beckham, and all the sissy Italian National team members) receive more then plenty of exposure, have more money and fans they could ever handle. So, they simply don't give a flying rats ass about some domain. I mean when Bill Gates doesn't care about BillGates.com, why would some Poborsky care? In my opinion, the best you could ever hope is $50 from some big fan of his. But honestly speaking, even that is a big stretch, especially so with each passing day.
By the way, UltSearch has ZinedineZidane.com... Now, that's a domain I like
P.S.
David Beckham has 236k in Overture, and 1500+ with dot com extension, and yet there's no site there for years. What a freaking waste of an amazing pop-culture domain. Idiots!!
