Arsenal have signed Poland defender Jakub Kiwior from Serie A side Spezia on a "long-term" contract.
Brazilian defender Gabriel has played every Premier League game so far this season and Kiwior matches the profile of player the club are trying to sign.
Kiwior has won nine caps for Poland and started all four of their matches at the 2022 World Cup in Qatar.
He was pictured next to the Arsenal sporting director, Edu, during Sunday's 3-2 win over Manchester United in the Premier League.
Kiwior is the second player to join the Premier League leaders this month after a £21m deal for striker Leandro Trossard from Brighton.
