As of now, there are no public records or credible reports indicating that Nigerian Afrobeats star Fireboy DML has stated that Ghana's Black Stars are better than Nigeria's Super Eagles. Such a statement would likely attract significant media attention, especially given the longstanding football rivalry between the two nations.​

However, it's worth noting that other public figures have expressed opinions on this topic. For instance, in November 2022, BBNaija star Pere Egbi praised the Black Stars, describing them as "much better" than the Super Eagles following Ghana's performance against Portugal in the 2022 FIFA World Cup. He highlighted Ghana's skillful play during the match, despite their 3-2 loss to Portugal. ​

Historically, the rivalry between Ghana and Nigeria has been intense. In March 2022, the Black Stars secured a spot in the 2022 FIFA World Cup by drawing 1-1 with Nigeria in Abuja, advancing on away goals. However, in a more recent encounter in March 2024, the Super Eagles defeated the Black Stars 2-1 in an international friendly, marking Nigeria's first win over Ghana in 18 years. ​

If Fireboy DML has made such a statement, it has not been widely reported in mainstream media. For the most accurate and up-to-date information, it's advisable to consult official interviews or statements from the artist.
