Lukaku scored his second goal of the season after arriving from Manchester United as Inter defeated Cagliari 2-1 but the victory was soured by racist chants.

Monkey chants were directed at Lukaku as Inter's club-record signing stepped up to convert a 72nd-minute penalty at the Sardegna Arena.

Amid widespread condemnation, Lukaku told Inter TV: "I'm very happy about these first two league victories and about tonight's success.

"It was a tough match, we had to fight but that's what we'll have to do in every game, I'm happy for the team and for our fans.

"To score wearing this shirt is a great feeling, I want to help the team even more, through assists too: the goal is to continue like this."

Lukaku scored the winner after team-mate Lautaro Martinez's first-half opener was cancelled out by Joao Pedro away from home.

On his partnership with Martinez, Lukaku added: "It's improving week after week and I'm happy about his goal, which was important for us.

"Now there will be a break for national team commitments, it will be important that we all come back in good condition and then work best in preparation for the matches at San Siro against Udinese and Slavia Prague [in the Champions League]."
