West Ham United Academy defender Filip Modelski has been included in the Poland Under-18 squad for a home friendly double-header with Sweden next month.
Modelski will join up with his international team-mates for a training camp on 8 August ahead of meetings with the Swedes in Koszalin on 10 August and Szczecinek on 12 August.
The right-back, 17, has been a regular for his country at age-group level, featuring in U18 friendly fixtures against Bulgaria and Belgium last season.
Modelski joined West Ham from Polish club Arka Gdynia in the summer of 2009 following a successful trial.
The defender's Academy team-mate, Deniz Mehmet, is preparing for Turkey's U18 friendly double-header with Estonia next week.
Mehmet will join up with his international team-mates in Istanbul ahead of the fixtures, which will take place at the Ozel 2 Mac stadium on Tuesday 13 July and Thursday 15 July.
The 17-year-old's call-up is the latest step in what has already been a successful international career for the London-based stopper.
Mehmet, who has a Turkish father, was part of his nation's squad at the 2009 UEFA European U17 Championship finals, keeping a clean sheet as Turkey defeated England 1-0 in the group stage.
Later last year, the goalkeeper played four times as Turkey reached the quarter-finals of the FIFA U17 World Cup in Nigeria before losing to Colombia in a penalty shoot-out.
