Inter Milan boss Antonio Conte defended Romelu Lukaku after defeat to Juventus.
Lukaku struggled to make an impact on the night.
But Conte insisted: "He is definitely a player who has to train, he has an impressive physical size, he needs to train and play to be in great condition.
"In the beginning he had this problem in his back.
"I think he gave everything, it is inevitable that with Barcelona we lacked Lukaku.
"Romelu is committed, he has tried to do his best. I hope he overcomes these small problems."
