Nottingham Forest have boosted their promotion push with the signing of Iran international Karim Ansarifard.

The striker, who scored the equaliser for his country in their 1-1 draw with Portugal at the World Cup, joins from Olympiacos.

Both Forest and the Greek giants are owned by Vangelis Marinakis and the 28-year-old is reported to have signed an 18-month deal with the Midlands club.

Forest are seventh in the Championship table, two points outside the play-off places, having won one of their last three games.

Aitor Karanka's men are in action at home to league leaders Sheffield United on Saturday.
