Whilst still playing for clubs in the United States, he became chairman of Polish club
Górnik Konin in 1999. Manager
Jerzy Kasalik was sacked by Nowak for unexplained reasons, despite their first place in the league, and he appointed little-known manager Jarosław Kotas. The team soon started to lose matches at an alarming rate and only just managed to escape relegation, only thanks to their good start. The 1999–2000 season proved to be a disaster. The owners decided to rename the senior team
KP Konin, whilst the reserve and junior teams used the old
Aluminium Konin name. The club finished dead last. It then turned out that in the second half of the season plans to relocate the team to
Bydgoszcz were put in place, and played under the name
Zawisza SSA. In the end the relocation never came to fruition, but the team, which only amassed 8 points the entire season, was disbanded, with the club management and the chairman Piotr Nowak widely held responsible. The reserve team, which that same season was relegated from the
Third Division, became the first team, and a season later (2000–01 season) managed to gain promotion, going straight back up. Under the lead of Jerzy Kasalik, the team achieved a back-to-back promotion to the
Second Division, restoring the club's place after the first team was disbanded. The success however was short-lived, after in the 2003–04 season the club finished last once again. Following their relegation, many of the Aluminium players were involved in the large
corruption scandal in Polish football which shook the country that season, which had a major impact on the club sponsors who all withdrew. This meant that the new club couldn't even afford to play in the then regional
Third Division, and the senior team was disbanded. ==Coaching career==
