The Hammers want to do business for around £10m, while Sunderland rate Rigg at £20m.
However, any move will be dependent on whether Sunderland clinch promotion from the Championship this season.
Rigg would prefer to experience the Premier League with his hometown club, though could move if Sunderland miss out.
