Sunderland are inviting offers for Kieran Richardson.

The Times says Richardson has been offered for sale to Tottenham Hotspur, Birmingham City and Fulham.

The Sunderland winger has started 15 Barclays Premier League matches this season, mostly in midfield, but the 25-year-old has been unhappy with an occasional role at left back.

Richardson has attracted interest from Bolton Wanderers and Newcastle United since moving to the Stadium of Light from Manchester United for £6 million three years ago.
