Sunderland target Neven Subotic could stay in the Bundesliga, despite significant interest from the Premier League.
Centre-half Subotic will leave Borussia Dortmund this summer and that has sparked interest from several Premier League clubs, including Sunderland, Stoke and Liverpool.
However reports in Germany today have indicated that Cologne are leading the race for the 27-year-old and are ready to make a £4million move.
Sam Allardyce is eager to boost his options at full-back, as well as centre-half, with Sunderland continuing to be linked with Lille right-back Djibril Sidibe.
Reports in France say Monaco are in talks with Sidibe, but Sunderland could still hijack the move, although Lille are mooted to have set a £12m asking price.
Meanwhile, Sunderland remain firmly in the hunt to sign West Ham frontman Diafra Sakho after seeing a bid rejected earlier this month.
Sakho - who has a £15m price tag on his head - is still among Allardyce's main targets to boost his attacking options, but West Ham want to bring in another frontman themselves before sanctioning the 26-year-old's exit. Read the full story here.
Allardyce needs extra firepower, with Jermain Defoe currently the only orthodox central striker at Sunderland's disposal after the departures of Dame N'Doye, Steven Fletcher and Danny Graham.
Fletcher could be heading to relegated Norwich City, with reports that the Canaries are eager to sign the Scottish international on a free transfer.
