Sunderland are in talks with Rennes striker Asamoah Gyan.
PA Sport says Sunderland have opened formal negotiations with French club Rennes over a club record move for Ghana international striker Gyan.
Their need became more acute on Sunday when Fraizer Campbell, who had been partnering Darren Bent, suffered suspected knee ligament damage during the 1-0 Barclays Premier League victory over Manchester City.
Gyan, 24, an international colleague of on-loan defender John Mensah, was one of the stars of the World Cup finals and has been in manager Steve Bruce's sights all summer.
