Celtic have signed central defender Maik Nawrocki from Legia Warsaw for an undisclosed fee.
The 22-year-old has agreed a five-year deal with the Scottish champions.
Nawrocki made 30 appearances, all but four of them starts, for the Polish Ekstraklasa runners-up last season, scoring four goals.
The Bremen-born defender came through Werder Bremen youth ranks and transferred to Legia Warsaw permanently last summer after a year on loan.
Nawrocki, who also helped Legia win the Polish Cup last season, was a substitute as they beat champions Rakow Czestochowa on penalties after a 0-0 draw in this season’s Polish Super Cup.
However, he did not feature in Friday’s win over LKS Lodz at the start of the domestic league campaign.
