Tuscan coach Leonardo Semplici is convinced Romelu Lukaku will take Inter Milan to another level.
The former Inter centre-forward is returning on-loan from Chelsea.
Semplici told La Gazzetta dello Sport: "Lukaku will be devastating. He's going to increase Inter's value.
"He has great desire and determination and when he was there he felt all right. He wants to come back after an unhappy experience at Chelsea."
Semplici also commented on Paul Pogba's imminent return to Juventus from Manchester United.
He added, "Pogba, on the other hand, returns to Juve with great conditions: and with a mentality."
