A report in the Sunderland Echo has claimed that Sunderland remain interested in signing Diafra Sakho, but their move for the West Ham United striker is currently being held up by his current club.

The Echo claims that the Black Cats have already had a bid rejected for the 26-year-old, for whom the Hammers want £15m, but Sam Allardyce - who was the manager that brought Sakho to the Premier League - is still keen to reunite with the forward at the Stadium of Light.

The Echo reports that any move for the Senegalese however, is going to be held up until the Irons have secured a replacement for Sakho, with Ligue 1 pair Alexandre Lacazette and Michy Batshuayi both being linked with moves to the Olympic Stadium.

It would be a major risk for Slaven Bilic to allow Sakho to move on currently, especially if he was to join a team in the same division. Without him, West Ham have just Andy Carroll and Enner Valencia in terms of senior striker options, and the latter's form in particular has hardly been encouraging since his move to England.

Though Sakho's form last season was equally uninspiring, he proved during his first campaign with the club that when he is given a prolonged run in the team, he can be ruthless as he scored in six consecutive league games and finished the year with 10 goals in just 23 league appearances. 

And Allardyce will be hoping that the Hammers can get a deal done for another forward quickly, so he can press on with a move for Sakho and help him rediscover his best form ahead of the new season.
