"Arsenal" profitably sold an unused Pole

London's "Arsenal" team managed to profit by saying goodbye to a player who had not played in their ranks.

It was officially announced that the "Gunners" sold defender Krystian Bielik to "Derby" club for 10 million pounds sterling.

The member of Poland's U-21 national team arrived in London in 2015, when he left Warsaw's "Legia".

Unfortunately for the player, he did not get a single chance to play in a "Premier League" championship match in several years.

Last season, A. Bielik was loaned to "Charlton Athletic" team.
