In Poland there are many, but two are standing out from the crowd - Wojciech Fibak (former ATP player) and Adam Romer (editor-in-chief of "biggest Polish magazine about tennis" - TBH, there's only one about tennis ). They starts their predictions every time when Polish player starts winning.
Example? Both already said that Radwanska is RG favourite
Fibak is not that bad, but Romer is awful. Also I can't stand old Tomaszewski and his reflections about Wimbledon 1933, he seems to have a butthurt, like in the title of his book "I wanted to win Wimbledon" Also I do not like Choynowski, Grzybowska, Sakowicz-Kostecka, Straczy and Katarzyna Nowak, and that one guy with weird accent who is talking during rallies, that tennis player X was banging tennis player Y. Oh, and of course Stopa with his prejudice to Domachowska in 2003.
Every commentator who isn't a tennis player (with the exception of Manuel Poyán ) They all got there because they're friends with someone, I say this because they have no fucking idea of tennis at all; I mean instead of W T A they say "weeta", go figure
The belief that man is an irresolute creature pulled this way and that by two forces of equal strength, alternately winning and losing the battle for his soul; the conviction that human life is nothing more than an uncertain struggle between heaven and hell; the faith in two opposed entities, Satan and Christ - all this was bound to engender those internal discords in which the mind, excited by the incessant fighting, stimulated as it were by the constant promises and threats, ends up by giving in and prostitutes itself to whichever of the two combatants has been more obstinate in its pursuit. Life isn't black and white, it's gold.
There are so many I can't even remember them all.
One that surely stands out is Vincenzo Martucci, who writes for the most prestigious sports newspaper in Italy but he's totally clueless (and he speaks an embarrassing, macaronic English too).
