Romelu Lukaku failed to make any significant impact on his return to Chelsea.
The Belgian forward returned to Stamford Bridge last summer in a £97.5million deal but failed to prove his worth at the West London club.
He scored only eight goals in 26 Premier League matches and was often benched by Tuchel in favour of Kai Havertz playing the false nine role.
This summer he returned to San Siro on a season-long loan and intends to prove his critics wrong.
“The (last) season at Chelsea gave me extra motivation to do even better than before,” Lukaku said in an interview with DAZN Italia.
“I think in one year everyone has forgotten about the things I am capable of doing on the pitch. That is a kind of anger that I have inside me.
“That now the [Inter] team has it too, which didn’t win last year, all together we hope to do better and bring something home.
“So many things [went wrong]. I think before, when I left [Inter], I wanted to take revenge at Chelsea because when I was young it was my team for 11 years.
“I had the opportunity to go back there and thought I would be a hero, but that wasn’t the case.”
