Chicago Fire’s Gabriel Slonina — who is viewed as the future US national team goalie — is listed on Poland’s roster

The Chicago Fire’s Gabriel Slonina, an 18-year-old viewed as a goalkeeper of the future for the U.S. national team, was listed on Poland’s 39-man roster announced by coach Czesław Michniewicz on Tuesday ahead of four Nations League matches next month.

Slonina, who turned 18 on Sunday, became Major League Soccer’s youngest starting goalkeeper last Aug. 4 at 17 years, 81 days, in a 0-0 draw against New York City. He started 11 league matches last season. including the final 10, and has started the first 11 this year.

Born in Addison, Ill., and of Polish descent, Slonina attended U.S. national team training camps in December and January but did not get into any matches. He has played for the U.S. at several youth national team levels.

[ [Don’t miss] Gabriel Slonina is making waves — and not only for becoming the Chicago Fire’s ‘scary’ good goalkeeper. The Addison native’s unrelenting work ethic and maturity are well beyond his 17 years. ]

Under FIFA rules, a player may appear into up to three matches for a national team before turning 21 without being tied to the team.

Slonina is among five goalkeepers on Poland’s roster, joining starter Wojciech Szczęsny of Juventus and Bartłomiej Drągowski of Fiorentina, Kamil Grabara of Copenhagen and Łukasz Skorupski of Bologna.

Zack Steffen of Manchester City and Matt Turner of New England, who is transferring to Arsenal this year, shared the U.S. starting job during World Cup qualifying, and Ethan Horvath and Sean Johnson also were on the roster.
