Romelu Lukaku has become the latest footballing star to receive vile racist abuse from opposing fans – with Serie A side Cagliari the guilty party once again following their despicable act towards Everton new boy Moise Kean during his time as a Juventus player just a few months ago.

Playing for Inter Milan after leaving Manchester United this summer, Lukaku scored the winning penalty in a 2-1 victory at Cagliari on Sunday.

As he stepped up to take the spot-kick, some Cagliari fans could be heard making monkey noises at him from behind the goal.

Following the match, Lukaku wasn’t asked by Inter Milan’s in-house TV channel about the incident – despite the clearly audible and sad scenes.

However, his team-mate Milan Skriniar – who was seen putting his fingers to his lips to the Cagliari fans – did air his disappointment. ‘There are things that must not be in football, but unfortunately there are almost always still,’ he said.

After converting the penalty, Lukaku simply stared at those who had been making the noises, as his team-mates rushed to congratulate him.

After Sunday’s incident involving Lukaku, Inter boss Antonio Conte addressed the issues in a press conference.

‘I really didn’t hear anything from the bench. However, it is true that in general in Italy more education is needed. I think that in Italy we must improve a lot and be more educated and respectful towards those doing their job.

‘In other countries you support the team, you don’t insult the opposition like this. There must be the maximum respect.’
