The UEFA U21 European Championships in Poland begins in seven days, and Arsenal will have four representatives from three different countries at the summer tournament.

Each participating nation has submitted their final 23-man squad that will compete for the  trophy. The tournament starts with the first game of Group A on June 16 and the final will be played on June 30.

Hosts of the tournament, Poland, will participate in Group A along with England, Slovakia and Sweden who are the defending champions.

Group B consists of FYR Macedonia, Portugal, Serbia and Spain.

In Group C, Czech Republic will take on Denmark, Germany and Italy.

Arsenal will have four representatives from three different countries at the tournament – Krystian Bielik, Hector Bellerin, Rob Holding, and Calum Chambers.

Krystian Bielik received his first call-up for the Poland u21 squad, and the centre-back will be hoping to put on a good performance in front of his home crowd. Bielik impressed in the second half of the season while on loan at Birmingham City and will be hoping to carry on such fine form on the international stage.

Hector Bellerin is 22 but has been called up to the Spain u21s. The right-back has been a regular in the Arsenal first-team and has been tipped to become a regular for Spain in the future.

Rob Holding and Calum Chambers have both been included in the final squad for England and they are both expected to make decent performances, with Chambers likely to be first-choice.
