According to a report in the Sunderland Echo, Sunderland could receive over £3 million for Sebastian Coates.
The Uruguayan defender appears to be heading for the exit door at the Stadium of Light, after failing to impress Sam Allardyce.
Coates appeared to in Allardyce’s first team plans when he was first appointed, but a series of disappointing performances have seen the former Liverpool man slip down the pecking order.
Wes Brown and John O’Shea have both played more regularly than Coates recently, while they have also signed Jan Kirchhoff from Bayern Munich in January.
Sunderland are hoping to complete a deal for Lamine Kone in the coming days, meaning that Coates’ chances of breaking back into the starting line up look slim.
As a result, Allardyce is willing to sell the 25-year-old and the Sunderland Echo suggest that Sporting Lisbon are happy to part with over £3 million to sign the centre back.
