Blaszczykowski - right winger in Borussia Dortmund, 2007/08 and 08/09 he was amazing, used to score great goals against Bayern, nowadays he's somewhat worse but still is a right wing regular
Boruc - former Celtic keep, but well, after all the divorce stuff he kinda lost it, Strachan and Celtic coaches used to say that he is up there with Buffon in terms of skill, now he's in Fiorentina already supposed to be causing trouble during training sessions
Obraniak - left winger currently in Lille if I remember well, not too bad, but also not that brilliant,
Jelen - striker, I think last season he was in a top 5 of topscorers in Ligue 1, Auxerre, rumored to be moving to Juventus, but he decided to re-sign
and of course keeps in MU and Arsenal (which used to be known for potential but didn't deliver, especially Fabianski). Szczesny (the third keep for Arsenal) is also really young and promising. Wenger said he is likely to be 1st team regular for Arsenal one day if he keeps up his improvement.
Don't you lot dare to make fun of this magnificent nation !
