American NBA stars have mocked world sprint king Noah Lyles on social media over comments saying he is offended when teams declare themselves "world champions" for winning an NBA crown.

U.S. sprint star Lyles won the 100- and 200-meter titles and helped the U.S. 4x100 relay capture gold at the World Athletics Championships in Budapest.

But Lyles said he is offended when U.S. sports league champions like those in the NBA declare themselves "world champions" after capturing a crown without facing global rivals.
