The 25-year-old joined Borussia Dortmund from Wisla Krakow in the summer of 2007, but is currently not getting regular first-team football at the German side.
“I am not satisfied with the way I’m being used at the moment. I get upset when I don’t play,” the winger told Polsat.
“Let’s just wait and see how things develop before December. Some things could change over time. When I don’t get the chance to prove my worth, I might have to look elsewhere to get playing time.”
Blaszczykowski’s current contract with Borussia Dortmund is set to expire in the summer of 2013.
