Romelu Lukaku's form and fitness have been a real concern for Belgium ahead of the World Cup, having badly struggled for Napoli on and off the field this season.
But the veteran striker showed his enduring class, after coming on for a late cameo, with an injury-time strike to seal a deserved 2-0 victory for Belgium against fellow participants Croatia.
Captain Youri Tielemans gave Belgium the lead with a neat first-half effort, with Hans Vanaken also heading into the crossbar.
It was Lukaku's first international appearance in more than a year. The 33-year-old has played just 64 minutes for his club this season due to a hip niggle.
"This is ideal for Romelu, but also ideal for the team," Belgium captain Youri Tielemans told VTM.
"We know how important he is to the group.
"He is sharp and mentally everything is fine too.
"We are going to need him very badly," Aston Villa midfielder Tielemans added.
