The Belgium international had fleeting opportunities last season in the club’s first-team and spent large periods of time on the bench.
However, after the powerful attacker scored a brace for the Blues in a 4-2 win over Seattle Sounders in pre-season, Lukaku took a swipe at former boss Andre Villas-Boas and admitted that he is raring to go for next term.
“Those goals have been a long time coming. Last season was very difficult for me,” he confessed to The Sun.
“But now it’s back to zero and if you have a good manager behind you, like I do now with Roberto Di Matteo, it’s the perfect situation. I’m confident and sure I can do well.”
Lukaku has been linked with a loan move to another club this summer, but the Blues are still light in attack after seeing Didier Drogba and Salomon Kalou depart at the end of last season.
