Sunderland sign Diouf from Bolton

Sunderland manager Roy Keane has continued his summer spending spree by completing the signing of Bolton forward El-Hadji Diouf for an undisclosed fee.

The 27-year Senegal international has agreed a four-year deal with the Black Cats after spending four seasons at the Reebok Stadium.

Diouf becomes Keane's fifth signing of the summer following the arrivals of Teemu Tainio, Nick Colgan, David Meyler and Pascal Chimbonda.
