The German sportswear company Adidas is concerned that publicity generated by bribery allegations over the awarding of the 2022 World Cup to Qatar risks damaging football.
FIFA is conducting an internal investigation into the decisions to hold the 2018 World Cup in Russia and the 2022 Cup in Qatar, and Adidas has released a statement expressing its confidence about the matter being dealt with as a priority.
Adidas has a long-term sponsorship with FIFA that runs until 2030.
Fellow sponsor Sony has called for a "thorough investigation" into the bribery claims first reported in Britain's Sunday Times newspaper.
Both Qatar and Russia deny any wrongdoing.
