Jakub Antczak, a 22-year-old Polish attacking midfielder and product of the Lech Poznań academy, has completed a move to second-league team Sokół Kleczew. Antczak, who had previously made his debut for Lech's senior team, spent the last season playing for their second team in the third league. The player decided he wanted a change after the conclusion of the previous campaign and has now joined his new club on a free transfer. He has been capped once for the Poland U19 national team.
