Robert Lewandowski may have played his last game for Poland.In an X post on social media, the superstar striker vowed he will not play for the nation again until manager Michal Probierz departs.Lewandowski has made a bold pledge regarding his international futureGettyHe wrote: “Considering the circumstances and the loss of trust in the coach of the Polish national team, I decided to resign from playing in the national team.“I hope that I will be able to play for the best fans in the world.”Lewandowski was absent from Poland’s squad for their June international fixtures and told Polish outlet TVP Sport it was due to being ‘mentally tired’.“I know that I am often judged as a professional, not a person,” Lewandowski said.“Returning from injury, I played two league games and told coach Probierz that I did not feel good physically, but especially mentally.“With all due respect to journalists, none of you thought about the fact that you can be mentally tired.“Who among you can know better how I feel?”Polish fans have shared differing perspectives on the Barcelona striker’s bold stance.One fan wrote on X: “Bravo! I hope this decision will open eyes not only in the context of firing the coach but also in the context of a change at the very top in the PZPN (Polish Football Association).”But another supporter took a stronger and disapproving view.A taxing campaign for Barcelona seemingly took its toll on LewandowskiGetty@lewy_official - XHis post on X garnered plenty of attention as fans wait to see what’s next[/caption]They posted: “Don’t come back. You’re a mercenary who cared more about his own good than the country.
