He was one of two Poles in the title-winning side of 1995, with fellow countryman Józef Wandzik keeping over a dozen clean sheets (shutouts) during the season.
On 3 April 1996, Warzycha scored probably the most important goal of his career (according to a late interview), against Ajax Amsterdam in 1995–96 UEFA Champions League Semi-Finals in Amsterdam Olympic Stadium [1] and gave Ajax their first home defeat in four years, in their last home match before the demolition of the stadium.
His appearances in the UEFA Champions League have been no less impressive – he scored six goals in Panathinaikos' nine games on the way to the semi-finals of the 1995–96 competition.
With eight goals scored in all UEFA Champions League games, Warzycha remained the best scorer of Polish nationality in this competition until the 2012–13 season, when Robert Lewandowski scored 10 times for Dortmund in Dortmund's surprise run to the Champions League final.
