The Borussia Dortmund right-back missed six months of action with a hip injury but is feeling no ill effects after returning to the field and is happy to be "100 per cent"
The right-back underwent surgery back in June and then completed a lengthy rehabilitation programme before at last making his return in the 3-0 defeat to Bayern Munich in November.
His absence coincided with a host of injuries to key first-team players at Signal Iduna Park but, having made a further 13 appearances for Dortmund this term, Piszczek insists that he is fully fit once again.
He told derwesten.de: "For two weeks I was in the phase where it was all about getting my fitness back and moving forward again but now I can say that I'm not missing anything. I'm 100%."
Last season the Poland international enjoyed a fruitful partnership with Jakub Blaszczykowski down BVB's right flank but the 28-year-old admits that he is still working on his understanding with summer signing Pierre-Emerick Aubameyang.
"With Kuba we could understand one another without words. Auba is a little bit more difficult," he confessed. "We have not had a lot of game time together but we look better with every game."
Dortmund will continue their battle for second place in the Bundesliga when they host Borussia Monchengladbach on Saturday.
