Birmingham have captured Honduras international Carlos Costly on loan until the end of the season.
The Blues have shelled out £500,000 to Polish side CKS Belchatow in order to complete the temporary switch.
The Championship outfit will, however, have the opportunity to make the move permanent in the summer.
Costly arrives with an impressive track record, which includes six goals in 22 appearances for his country.
Blues manager Alex McLeish told his club's official website: "Carlos has a smashing pedigree, especially with the Honduran national side. They are an emerging country who can still qualify for the World Cup in South Africa.
"In recent times, they have taken some fantastic scalps - including a result against Mexico - and Carlos is a key figure in the team.
"He is a target man-type striker, who is hungry and has loads of bottle. He has channelled aggression and wants to get in where it hurts."
