"I never thought at the time that I would end up signing for Spartak but it's funny how football works out," he said.
"But that game against Spartak was one of the great European nights at Celtic Park."
New Celtic signing Lubos Kamenar has also said his move to the Glasgow club has created huge interest in his home country of Slovakia, also home to former Celtic players Lubo Moravcik and Stan Varga.
The Slovak international goalkeeper moved on a season-long loan from Nantes on transfer-deadline day.
"All of the people in Slovakia are proud of Moravcik and Varga and now I am following in their footsteps," he told the club's official website.
"There is huge interest back home in my country about the transfer because it´s Celtic."
