Arrival of Romelu Lukaku from Inter Milan for a club-record £97.5m pushed the player further down the pecking order and all but ended the possibility of him staying in the Premier League.
Fellow Serie A side Atalanta and Arsenal also expressed an interest in Abraham, but Chelsea’s preference was always to sell him to a foreign club.
Chelsea head coach Thomas Tuchel has accepted some responsibility for Tammy Abraham’s lack of opportunities last season as the striker’s future at Stamford Bridge lies in the balance.
“He was clearly not happy with the last half a year and maybe he has reason also not to be happy and maybe it was also my fault not to push him, not to trust him on the same level I maybe trusted other players.
“I can absolutely understand that he wants more minutes. So the decision will be ‘how do we plan, what are Tammy’s plans, does he fight his way back into the team from the position where he ended last season or does he want to change club to have the chance of being a regular starter?'”
