West Bromwich Albion are the latest club to show interest in former England midfielder Owen Hargreaves following his release by Manchester United.
BBC Sport understands the Baggies have made contact with Hargreaves' representatives but any potential future deal is at a very early stage.
Leicester boss Sven-Goran Eriksson, who managed the 30-year-old with England, is also exploring a possible deal.
Hargreaves is without a club after the end of his Old Trafford career.
Hargreaves has attempted to prove his fitness by posting videos on YouTube to attract clubs after only playing 39 games during his four years at United following a £17m move from Bayern Munich.
Albion manager Roy Hodgson is an admirer of Hargreaves and is ready to explore the possibility of doing a deal depending on his fitness.
Any deal for Hargreaves, wherever he restarts his career, is likely to be on a pay-as-you-play basis but Albion have not got as far as discussing any possible structure for a transfer after registering their interest.
The Canadian-born midfielder won four German titles and a Champions League winners' medal at Bayern Munich and played in United's Champions League win against Chelsea in Moscow in 2008.
