They say Chelsea are prepared to pay €50m for Dzeko and his team-mate Emerson Palmieri, who plays left-back.

Chelsea would let Roma have Michy Batshuayi on loan as part of the deal but the Italians are also asking for another €15m.

Dzeko moved to the Italian capital from Manchester City in August 2015.

The 31-year-old has scored 12 goals for Roma this season, including a double against Chelsea at Stamford Bridge in the Champions League in their 3-3 draw in October.
