Inter Milan defender Francesco Acerbi is convinced Romelu Lukaku can get back to his best.

Lukaku is aiming to be fully fit for the second-half of the season after a frustrating World Cup with Belgium.

Acerbi joined Inter last summer from Lazio.

“It takes him time to get back to his best condition because he is a very big and strong player," he said when asked about Lukaku's fitness.

“But it will depend on him in the end, and he's shown a great desire to get back to his best, because he's a great lad."
