Yesterday Romelu Lukaku at least temporarily silenced his critics.

The forward from Belgium scored a winning goal in the first leg of the quarter-finals, where "Inter" defeated "Porto" footballers with a score of 1:0.

However, the Belgian could not avoid criticism from "Inter" director Giuseppe Marotta before the match.

"Why does Lukaku start the match on the bench? Romelu carries 103 kilograms on his shoulders, he must be physically ready. He is not 100% ready, he is returning to his best form.

We expect a lot from Romelu in the second half of the season," Marotta said.

Meanwhile, after the match and after the winning goal, Lukaku jokingly responded: "Wow, look at me. I am in great shape, mamma mia."
