The 20-year-old spent the 2012-13 campaign at West Brom, scoring 17 Premier League goals during his stay at the Hawthorns.
But, after holding talks with returning Stamford Bridge manager Jose Mourinho, the striker is adamant that he will be a part of the club's first-team plans this season.

"You never know in football but my mind is on 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 XI.
"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."
Lukaku would not reveal the details of his conversation with Mourinho but has been buoyed by the discussions.
"Yeah, 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," he explained.
"We had a good talk and now it's up to me."
