El-Hadji Diouf is poised to join forces with Sam Allardyce again.
Blackburn boss Allardyce, who worked with Senegal striker Diouf for three years during his time in charge at Bolton, has agreed a deal - believed to be £2m - with Sunderland for the 28-year-old.
Diouf yesterday passed a medical, and providing he agrees terms and signs a contract today, he will go straight into the squad for the Barclays Premier League clash at Middlesbrough tomorrow.
With Diouf on the brink of signing, that has allowed Allardyce to release Matt Derbyshire to Olympiacos on loan until the end of the season.
"We're in the process of trying to sign El-Hadji Diouf at the moment," confirmed Allardyce.
"So the one-in, one-out scenario looks like it will be finalised this morning.
"He can play a few positions, down the right, down the left, as well as along the front.
"I'm hoping he can come and give me the kind of performances he gave at Bolton.
"At 26, he is in the prime of his career, so hopefully we will get that sorted today and get him in the squad tomorrow."Reuse content
