I think in 2007 it was the golden age of Polish team. Wacha was playing in singles his best. Also the XD Mateusiak & Zieba was ready to win vs top world pairs. And there were still two very good doubles: Logosz & Mateusiak and Augustyn & Kostiuczyk (Zieba). This WD won the Denmark Open 2006 and MD 4 times was in SF of European Championships and one time in QF of OG (Beijing 2008). The only relative weakness was WS. So in 2007 it was a peak when all these five players played at the top level. In 2009 the squad was not so strong (finished 15th) and in 2011 worse (finished 19.). Later Poland did not participated and was not in a position to prepare a good team. In 2010 the men's team was enough strong to win the silver medal during European Team Championships but the women's team was already poor. It was the XD Mateusiak/Zieba as you know who got the best results in the period 2008-2016 .
