Romelu Lukaku scores his 90th goal for the Belgian national team.

Belgium's Romelu Lukaku etched his name into history books by scoring his 90th international goal, a milestone that solidified his status within the Belgian national team.

Youri Tielemans capitalized on a defensive lapse to net the initial goal, and Romelu Lukaku seized the opportunity to notch his 90th Belgian national team goal, marking his return after a year-long absence from the squad.

Lukaku, now 33, unleashed a thunderous shot, silencing the doubts that had plagued him in Naples, where he'd played but not started a game all season due to a nagging hamstring issue.

In the 38th minute, a Croatian defensive lapse allowed Tielemans to score with ease from a short distance, courtesy of Jeremy Doku's energetic dash down the flank.

Both coaches seized the chance to test their full rosters, with Croatia utilizing all 10 of its designated substitutes and introducing Lukaku into the fray just 18 minutes from time.

Tielemans' corner in the 74th minute was met with a powerful header from Hans Vanaken, who struck it against the crossbar.

Ante Budimir's shot hit the crossbar in the second half, a close call that fell just short of finding its mark. Luka Modric had his scoring opportunity thwarted earlier by a precise block from Thibaut Courtois.

In a separate international friendly, Croatia is scheduled to face Slovenia in Varazdin on Sunday as part of their pre-tournament preparations. Meanwhile, the Belgian national team will be hosting Tunisia at the King Baudouin Stadium in Brussels on Saturday.

Belgium kicks off its Group G journey at the World Cup against Egypt in Seattle on June 15, as Croatia faces England in Dallas a day later, June 17.
