Birmingham City signed former Blackburn Rovers forward Matt Derbyshire on loan from Olympiakos on Monday.
The 24-year-old Derbyshire started only 10 league matches for the Greek club last season, scoring six goals, but was hampered by injury and had lost form by the end of the season.
"Olympiakos announced that an agreement has been reached with Birmingham for the loan of Matt Derbyshire for one year," said a statement on the Olympiakos website.
