Wigan are set to sign out of contract Senegal striker El Hadji Diouf who trained with the Latics earlier today. QPR boss Neil Warnock famously called Diouf a sewer rat after an incident in an FA Cup match when in charge of Crystal Palace last season and Diouf was also embroiled in a spitting incident when playing for Liverpool against Celtic in a UEFA cup clash a few years ago.
