The 34 year-old, who held the lesser EU version in 2012, is a former two-time champion in his home country with five stoppages to his name, but has struggled when making the step-up past domestic level in the past.
Rome-based Dieli has lost three from his sixteen contests since turning professional in 2007 and can count a split decision loss to dangerous French southpaw Sofiane Takoucht as his best career performance to date.
Up and comer Selby, 27, picked up the vacant title with an impressive stoppage win over ex-world title challenger Rendall Munroe in February and is highly-touted as a future world champion by promoter’s Matchroom Boxing.
The Welshman has gone from strength to strength since his stunning knockout of Stephen Smith in 2011 and looks to have far too much for Dieli on paper – which could potentially lead to the fight being a non-starter.
Parties are expected to be in private negotiations soon, according to the EBU, with more developments set to be outlined by Selby’s handler Eddie Hearn in the coming weeks.
