Super Eagles defender Chidozie Awaziem has joined Boavista on a permanent transfer from FC Porto.
The 24-year-old joined Boavista on loan last summer but the Portuguese sports club have now triggered the buy-out option for Awaziem.
Boavista paid Porto €5m to secure his services making the versatile defender the most expensive signing in the history of the club.
Awaziem may yet still leave Boavista with a number clubs in France interested in his services.
The Nigeria international made 27 league appearances for Boavista in the 2020/21 season.
He joined Porto in 2015 and made 10 league appearances for the first team.
Awaziem spent time on loan with clubs in France, Turkey and Spain.
