Bilic is said to be interested in offering Dzeko the chance to return to England

The Bosnian striker is currently at Roma having been deemed surplus to requirements at Manchester City.

The 29-year-old arrived in England from Wolfsburg in 2010 and after a difficult start racked up 46 league goals in his first four seasons.

But the arrival of Wilfried Bony and the emergence of Kelechi Iheanacho limited the opportunities in the first team for the forward last season.
