Cierzniak still dreams of an international career but recognises that Poland are well stocked for goalkeepers, with Southampton's Artur Boruc and Arsenal duo Wojciech Szczesny and Lukasz Fabianski all vying to be No.1 and a number of youngsters coming through.
Cierzniak believes he would have to increase his profile by switching clubs to have a chance of playing for his country.
However, the 30-year-old is enjoying life at Tannadice so much that he has no intention of leaving and is focused on helping United to finish the season strongly.
"The important thing is that I'm happy here, my family is living here and my club is doing well," he said in the Daily Record.
"I don't know about international football because Poland has strong goalkeepers. At the moment, Boruc may be injured but Arsenal goalkeepers Szczesny and Fabianski are playing well and there are also some good young ones in the Polish league.
"If I ever wanted to play in the national team, I would probably have to change my team.
"The people of Poland look at the Scottish league and it's not so popular, although they do have respect for it.
"But, to be honest, I don't care so much what people say. Of course playing for Poland is a dream but things are more important for me.
"Every day I enjoy going into the club. We have great facilities and that's important.
"We still have a chance to win the Scottish Cup, we still have a chance to finish second or third in the table and I'm still very positive."
