Football fans on social media are blasting Madrid supporters, labeling the chants 'disrespectful' to the Belgian star.
A roar went up from the crowd when Hazard kissed the badge on his new club's jersey, but sections of the crowd loudly chanted "Queremos Mbappe!", meaning 'we want Mbappe', during his unveiling in the stadium.
Hazard signed for Madrid less than a week ago from Chelsea on a five-year deal for a reported £130 million (A$237 million).
An impressive 50,000 supporters came to his official presentation at the Bernabeu where, after he passed his medical, club president Florentino Perez welcomed him as a new galactico.
The 28-year-old is widely considered one of the best players in the world, so the chants demanding a different star player have seen those fans described as 'ungrateful', 'disgraceful' and 'pathetic'.
