Nottingham Forest said on Friday the club had signed South Korea striker Hwang Ui-jo (29) from French side Girondins Bordeaux and loaned him out to Greek champions Olympiakos Pireaus for the rest of the season.
Hwang scored 11 goals for Bordeaux in Ligue 1 last season as they were relegated to the second tier.
The forward has 47 caps for South Korea.
Newly promoted Forest are 10th in the Premier League and host Tottenham Hotspur on Sunday.
