Former Chelsea manager Jose Mourinho is expected to be confirmed as Internazionale's new coach after Roberto Mancini's agent announced that his client had left the San Siro.
Mancini is leaving Inter despite guiding them to their third successive Serie A title earlier this month and his agent, Giorgio De Giorgis, is in no doubt that Mourinho will be the club's next boss.
He told Sportitalia television: "Roberto never expected it to end like this.
"As an outsider, I could rationally understand that something was not right, but that is the way things have gone.
"Roberto is very disappointed also because he has not yet finished his job - he wanted to try and win even more league titles, and maybe even the Champions League.
"Now Mourinho will arrive and he has only got to repeat what has happened in the last few years.
"Roberto is now considering making a statement to avoid gossip and it should be a statement praising the president and those who worked with him.
"Certainly he is shocked and has taken it badly. I have spoken with him and he sounded quite down, but it will get even worse."
Mancini has been linked with the vacancy at Stamford Bridge, created by Saturday's sacking of Avram Grant.
