Arsenal have signed Greece winger Christos Tzolis on “a long-term contract”, the Premier League champions announced on Thursday.

No fee was disclosed but British media reports said the 24-year-old had arrived from Club Brugge for £34 million ($45 million), with Tzolis effectively a replacement for Leandro Trossard following his move to Besiktas.

Arsenal’s third permanent transfer of the current window arrives 48 hours after the Gunners missed out on Morgan Rogers to city rivals Chelsea for a reported £117 million ($157 million) — a record for a British player.

England midfielder Rogers called Chelsea the “biggest club in London”.

Tzolis scored 43 goals in 108 appearances for Brugge and featured in the Belgian side’s 3-0 Champions League loss to Arsenal last season.
