The Hazard brothers enjoyed winding up Belgium teammate Michy Batshuayi during victory over Cyprus.
After the game, Thorgan told reporters of his pre-match message to Batshuayi and that he was unhappy that Manchester United striker Romelu Lukaku found the net to ruin the Hazard family's monopoly on Belgian goals that night.
"Before the game, we had told Michy he wouldn't touch the ball because we were going to play with each other all the time," Thorgan said.
"In the end, it's a shame Romelu [Lukaku] scored at the end, otherwise there would have only been the name Hazard on the scoresheet.
"Eden had told me to put in a good performance, and I think it was. It's just a shame I missed two chances, but it's not too bad to score once from three opportunities."
