Former Italy coach Arrigo Sacchi says AC Milan and Inter Milan have big question marks over their strikers.

The city rivals meet on Wednesday night in the Supercoppa.

Sacchi, on Inter striker Romelu Lukaku, said: "Lukaku was the star of another Inter: his return cannot yet be judged... But why spend money on having the best if you don't create, but only expect the mistakes of others?

"I think Lukaku has the right temperament, but he pays for the suffering of the last year and a half."

And on AC Milan's Charles De Ketelaere, he also said: "He enters the field almost like a loser. Confused. Scared. Better, however, not to give definitive sentences: foreigners always need time. Of course, now he is suffering and it shows."
