Swiss officials are opening up a criminal investigation against FIFA president Sepp Blatter over suspicion of criminal mismanagement.

BBC Sports reports Blatter is being investigated by the Swiss Attorney General. Blatter is suspected of misappropriation over a TV rights deal and a "disloyal payment" to European football chief Michel Platini.

Swiss officials said Blatter is cooperating with the investigation and has been interviewed. Blatter's lawyer, Richard Cullen, said that no financial mismanagement occurred.

Blatter secured a TV rights deal with former Caribbean football chief Jack Warner in 2005. Swiss officials believe that Blatter violated his duties and acted against the interest of FIFA and FIFA Marketing.

According to The Telegraph, Platini issued a statement about his $2 million payment from Blatter:

"Today I was asked by the Swiss authorities to provide information relating to the ongoing investigations surrounding FIFA. I have always been open to supporting the relevant bodies and authorities in their investigative work and therefore cooperated fully," Platini said.

He added, "Regarding the payment that was made to me, I wish to state that this amount relates to work which I carried out under a contract with FIFA and I was pleased to have been able to clarify all matters relating to this with the authorities."

"Today I also made clear to the Swiss authorities that since I live in Switzerland I am available to speak with them any time to clarify any matters relating to the investigations," he concluded.

With this bombshell, it is looking more likely that Blatter will be stripped of his presidency. The question is: Will he end up serving jail time?

There have been conflicting reports that Blatter may or may not have resigned from the presidency. In June, Blatter stated that he would resign from the presidency as soon as FIFA elects someone to replace him. According to reports, Blatter reconsidered his decision once the African and Asian soccer federations were pressuring him to stay. Many people believe that Blatter is just trolling with everyone.

2015 has not been good for FIFA. Earlier this year, seven FIFA officials were arrested in a raid at a hotel in Zurich. U.S. authorities later charged them, along with two other FIFA officials and five corporate executives, over allegations of racketeering, wire fraud and money-laundering conspiracies spanning 24 years. The only FIFA executive who wasn't charged with a crime was Blatter.

Former CONCACAF official Chuck Blazer admitted that he and other executives took a bribe from South Africa to host the World Cup in 2010. He was later issued a lifetime ban by FIFA.

So far, Blatter has not been charged with any crime, but will likely face trial in the coming months.
