Sunderland have been linked with a fresh move for Micah Richards - six months after first being credited with an interest in the Aston Villa defender.
Richards is available to leave Villa Park on a £5million clause after their relegation last season and reports today have indicated that Sunderland could offer the England international a return to the Premier League.
The Black Cats were linked with the 28-year-old in the January transfer window, but Villa were not prepared to let their captain leave at that stage.
A new right-back is one of Sam Allardyce's three main priorities this summer, along with a striker and attacking midfielder, after Sunderland saw a move fall through for Davide Santon earlier this month.
Sunderland have also held talks over Paris St Germain's Youssouf Sabaly, with a view to a season-long loan.
However, the uncertainty over Allardyce's future is delaying Sunderland's manoeuvres in the transfer market, with the Black Cats boss still firm favourite to become England manager.
