Leyton Orient have signed Chelsea midfielder Jimmy Smith on a two-year contract.

The 22-year-old spent three months on loan at Brisbane Road last season, playing 16 games.

Smith has represented England at Under-16, Under-17 and Under-19 level and has also had loan spells at QPR, Norwich and Sheffield Wednesday.

He only made one appearance for the Chelsea first team when he was selected by Jose Mourinho in 2006.
