The 30-year-old, who signed for £30.8m (€45.5m) in May, was quoted as saying his “game doesn’t suit Mourinho” and he is “ready to pack his bags” and go back to Italy.
But a Chelsea statement insisted the comments were misinterpreted from an interview in a Russian magazine. Shevchenko was reported to have said: “I feel at home and it’s felt like my team for a long time but unfortunately my game doesn’t suit Mourinho.
“Roman Abramovich is my friend but all he could do was insist on a loan deal instead of me being sold,” he said.
Shevchenko, who scored his first European goal for Chelsea in Tuesday’s 2-0 Champions League win over Levski Sofia, added he had not discussed his future with the club.
“But if it happens, I am ready to pack my bags,” he said.
“I’m a completely self-confident person. If I don’t suit somebody then I’ll go back to Italy and prove how good I can still be.”
The Blues’ record signing insists he has given only one interview in recent weeks to a Russian magazine called ProSport and yesterday reiterated his commitment to the club.
“I give 100% all the time and I am committed and hungry for success with Chelsea,” the 30-year-old said.
“I have total respect for the Chelsea club and fans as well as for football in England and the culture of the country.
“There are always good and not so good moments in sport, that’s normal.
“If that means there is opinion and criticism, I respect that.”
Shevchenko admitted in the ProSport interview he was unhappy with the start he made with the Premiership champions but denied that he was struggling to adapt to the rigours of English football.
