Italy World Cup striker Christian Vieri isn't surprised Manchester United didn't see the best of Romelu Lukaku.
Vieri hit out at the coaching in England when considering Lukaku's influence on Inter's Scudetto winning campaign this season.
He said, "I have always said that Lukaku was overweight in England. On the other hand, players don't train in the Premier League like here, they don't train as under (Antonio) Conte's orders.
"At Inter, Romelu he lost fat and gained mass, he grew physically and muscularly. These two years with the Nerazzurri have been devastating, Lukaku is now impregnable."
