The U19 Italy international is on the verge of joining the Premier League giants on a permanent €15m deal plus €5m add-ons.
According to the report, the promising midfielder is expected to leave for England tomorrow and will undergo his medical with the Blues on Thursday, August 18.
Inter must sell some of their most valuable assets to balance the books. Andrea Pinamonti has joined Sassuolo for circa €20m and Casadei is now on the verge of leaving the Serie A giants for a similar fee.
Inter didn’t reach an agreement to sell Milan Skriniar to PSG so the Slovakia international is now expected to remain at Inter.
Chelsea are also said to be interested in Denzel Dumfries, but Simone Inzaghi has made it clear that he does not want to see any of his stars leaving in the last two weeks of the summer transfer window.
