Saint-Etienne have signed Cameroonian midfielder Landry N'Guemo on a deal until the end of the season.

The 29-year-old joins Les Verts on a free transfer after leaving their Ligue 1 rivals Bordeaux in the summer.

He is not on Africa Cup of Nations duty and could therefore make his debut away at Rennes on Sunday, where victory could take Saint-Etienne joint top of the table.

N'Guemo, who started his career at Nancy, made 43 appearances during a loan spell at Celtic in 2009-10.

He has scored three goals in 42 international games and played for Cameroon at the 2014 World Cup in Brazil.
