The Belgium international has revealed he has held talks with Jose Mourinho about his future at Stamford Bridge and he is determined to establish himself in the Portuguese's first-team plans.
"We spoke and I want to keep it private because when you have confidential talks with the manager, it has to stay between you and him," Lukaku told Sky Sports News. "We had a good talk and now it's up to me."
Asked if he would consider another loan move this season, Lukaku said: "No, not at the moment.
"You never know in football but my mind is in Chelsea now and I have come back to do well in pre-season and if I do a good pre-season, I think I will have a place in the squad and hopefully in the starting 11.
"Last year I had a great season at West Brom and I think have the qualities to do it here, but it is up to me.
"If I don't do well here, then loan again."
