The 51-year-old played over 140 games for the Hammers between 1999 and 2003, scoring 51 goals before leaving for Charlton Athletic, and he is widely regarded as an icon by the club’s supporters.
Di Canio has managerial experience with Swindon Town and Sunderland, helping to keep the Black Cats up in the top-flight in 2013 before getting fired after six months.
He was linked with the Celtic job in May 2014 and did apply for the Bolton Wanderers and Rotherham United jobs, but remains without one.
