His heart is divided. Henry will go from being one of the men who contributed to France's 1998 World Cup success, to being part of the Belgium technical team that will look to sink the French side on Tuesday.
Since he joined Roberto Martinez as part of the technical staff, Harzard, De Bruyne and company have started playing with new style.
The advice that they are receiving from one of the best players of the last decade has been taken on board by the Belgium stars.
Lukaku even acknowledged that being able to count on Henry has helped him grow as a player.
What the Belgium players have learnt from training with a world champion who reached the peak of his performance with France, will be put into practice on Tuesday.
Henry became a legend of Les Bleus thanks to 51 goals in 123 international games.
He was not a consistent starter during the 1998 World Cup, but made and impact from the bench in the second and fourth round, as well as in the semi-finals.
Now, the French King of football is threatening his own people.
It's a tough position for Henry, who will have a bitter taste in his mouth if France loses, but will also be able to see his own players go through to the World Cup final.
