Conte was speaking at his first news conference since being unveiled as Chelsea manager.
“Chelsea belongs in the Champions League and we must stay there,” he said.
“I know only the road to take the club back to competing and winning the title – work, work, work.
“The coach is a tailor who must make the best dress for the team. Last season in 10th was a bad season, but we must think to the present.”
Conte, who took his first training session at the club on Wednesday, said the “right spirit” was vital for Chelsea as they push to get back into the Champions League.
