Fifa's key World Cup sponsors have expressed shock over the arrests in Switzerland and encouraged the football governing body to clean up, but none of them have threatened to pull out.

Of all the statements released by sponsors such as Coca-Cola, Adidas, Visa, Sony and Gazprom, Visa had the sharpest criticism for the football body.

Stopping short of cancellation of deals, Visa said it would "reassess our sponsorship" if Fifa does not address the concerns.

"Our disappointment and concern with Fifa in light of today's developments is profound. As a sponsor we expect Fifa to take swift and immediate steps to address these issues within its organisation," said Visa in a statement.

Others have voiced similar apprehension over the scandal in which 14 people were arrested for alleged money laundering and fraud. Seven of them were top Fifa officials.

Admitting the arrests have dented the image of the sport, Coca-Cola said: "This lengthy controversy has tarnished the mission and ideals of the Fifa World Cup and we have repeatedly expressed our concerns about these serious allegations."

McDonalds, a second-tier sponsor, said the company "takes matters of ethics and corruption very seriously" and the arrests are "extremely concerning".

Adidas, the German sportswear giant, which was the first to express dismay over the arrests, said: "We can only encourage Fifa to continue to establish and follow transparent compliance standards in everything they do.

"The Adidas Group is fully committed to creating a culture that promotes the highest standards of ethics and compliance, and we expect the same from our partners."
