The Pole says he is thrilled to have signed for Jackie McNamara's men and cannot wait to play in the SPFL having signed a pre-contract with Celtic in January 2012.
"I don't like to talk about it very much. The deal fell through and that was it -nothing more. It's in the past now," said the former Bolton, Slask and Tromso centre-half.
"It's the best thing for me to sign for Dundee United. It was a good lesson for me the six months I was out injured.
"I'm not trying to be funny but as a wise-guy once said 'it's not just about the success you get, it's more about how you rise up after you've fallen down.' It was a good lesson for me and my family.
"I look back at that more from the bright side than the dark side. I don't think I need to show anyone that I can play here in Scotland. I am a self-confident player.
"Right now, I just want to show Dundee United fans and the manager that they can trust me in the team. It's up to myself to do that."
