The transfer of French striker Jeremie Aliadiere may have fallen through, but Larissa sealed its acquisition of Slovak midfielder Jan Kozak on January 27, the Thessaly club announced.
Aliadiere failed a fitness test on January 27 and Larissa withdrew its offer to sign the ex-Arsenal and Middlesbrough striker, as it decided that signing him would entail a considerable risk.
However, the struggling Super League side confirmed the arrival of Slovak international Kozak, who had also had a spell at West Brom in England five years ago.
Kozak signed a contract until the end of the season with Larissa.
He has 25 caps and has scored twice for Slovakia.
