Dorrans was Livingston's 12-goal top scorer last season

West Brom have completed the signing of Livingston midfielder Graham Dorrans in a �100,000 deal.

The Scotland Under-21 international has penned a two-year contract at The Hawthorns, with a further year's option in the club's favour.

Dorrans, 21, could eventually cost the Premiership newcomers a further �150,000 depending on appearances.

Albion agreed the move for Dorrans with the Scottish League Division One side in January.
