The Poles will face off against Austria in their next qualifying fixture in Warsaw on Monday.
After four rounds of fixtures, Poland maintained a perfect record atop their qualifying group, with 12 points and no goal conceded.
Barring a disaster, Jerzy Brzęczek's men have all but guaranteed themselves a spot in the 2020 European championships.
Poland on March 21 opened their Euro 2020 qualifying campaign with a 1-0 away win against Austria. The Polish team three days later beat Latvia 2-0 in their second Euro 2020 qualifier at the National Stadium in Warsaw.
Poland on June 7 beat North Macedonia 1-0 at Toše Proeski Arena in the Balkan country’s capital Skopje. Three days later the Poles demolished Israel 4-0 at home in their fourth straight Euro 2020 qualifying win.
Fifty-five European teams were in December drawn into a total of 10 qualifying groups, five groups of five teams and five six-team groups.
The Euro 2020 qualifiers will be played until November, with the top two teams from each group qualifying directly for the championships.
The Euro 2020 tournament will be held from June 12 to July 12, 2020 in 12 cities around Europe, with the final played at London's Wembley Stadium.
Brzęczek took over as Poland manager last summer after the national squad’s early exit from the World Cup in Russia.
