Former Cagliari and SPAL head coach Massimo Rastelli says the arrival of Romelu Lukaku makes Inter Milan title favourites.

The striker has returned to Inter on-loan from Chelsea.

"Lukaku will shift the balance also because he already knows the league," Rastelli said, “he's already won here and is much-loved, even if no one expected him to leave last summer."

“He's a formidable player and will once again be at the heart of things.

"He'll figure out what it takes to make the difference."
