Lukaku is already off the mark after scoring in victory over Lecce.
“He is fired up and determined, he has so much desire to do well. We found him as we left him, in fact he's even more determination," said Darmian.
“When you play for Inter, the goals are always important. We will give fight until the end, like what happened last year."
Darmian also says the Nerazzurri players are united with the new season underway.
“We focus on the pitch, we try not to listen to what happens off it."
