[4] Yaman won the bronze medal in the +70 kg semi-contact category at the 2012 WAKO World Kickboxing Championships for Cadets and Juniors held in Bratislava, Slovakia.

Beating her Brazilian opponent Caroline Santos 21–7 in the final match, Yaman protected her title as the world champion she won in 2015 and became the first Turkish female athlete to win the gold medal twice in taekwondo.

Hatice Kübra İlgün defeated Yaman in the 2019 Russia Grand Prix Final, which was announced as a selection by our Federation, and won the silver medal at the end of the tournament.

When we analyze the competitions of our two national athletes against each other, Hatice Kübra İlgün has a 2-1 advantage over İrem Yaman.

When all this information is analyzed, Hatice Kübra İlgün was determined to represent our country in the 57 kg category at the 2020 Tokyo Olympics.

[15] Yaman, who could not accept the defeat in the Moscow Grand Prix Tournament, made unfortunate statements to the press and targeted her teammate.
