• Joined Ruch's youth department at 16 and made rapid progress, reaching the first team at 18 and making his Ekstraklasa debut on 10 August 2008 as a late substitute against Górnik Zabrze.
• Scored the first of his two 2008/09 Ekstraklasa goals on 12 September against MKS Cracovia Kraków; ended that season playing in the Polish Cup final, which Ruch lost 1-0 to KKS Lech Poznań.
• Scored ten league goals in 2009/10 to finish fourth in the Ekstraklasa hit parade (Robert Lewandowski, of Lech, was top with 18).

FSV Mainz 05.
