The striker for Inter Milan left Chelsea on loan in the summer after a rough year in the Premier League.

Back in Italy, injuries have slowed him down, but he looked like he was back to his best at the start of the season.

Fans of Inter will be hopeful that he is ready to play when he comes back after the picture with Calvin Klein.

On the fashion brand’s Instagram story, the 29-year-old stood in their micro stretch knickers and looked ripped.

Lukaku only wore black briefs to show off his six-pack and tall frame.

Lukaku is the latest football star to show off Calvin Klein shorts. Son Heung-min, a star player for Tottenham, did the same thing for the fashion brand.

When the Belgian played in England, he was attacked for being too heavy, and Lukaku has even responded to those who said bad things about him.

It was said that Inter even put him on a diet when he got back to the San Siro.

He scored in the Nerazzurri’s first Serie A game of the season, a win over Leece, making him look like he was back to his best.

But Lukaku has missed a few games because of a thigh strain. He also missed important Champions League games against foes AC Milan and Bayern Munich.

In a big game on Saturday against Jose Mourinho’s Roma, he will hope to be back.

Fans of Inter love him because he played so well for the club for two years and scored 47 goals in 72 Serie A games.

It’s very different from his time at Chelsea, where he had problems with the manager, the fans, and regularly failed to score after moving for £97.5 million.
