A top US investigator has said he is "fairly confident" there will be more indictments in the FIFA corruption scandal.

It comes after Sepp Blatter was re-elected for another term as president of world football's governing body, despite widespread calls for him to step down in the wake of the controversy engulfing the organisation.

Richard Weber, head of the Internal Revenue Service's criminal investigations unit, told the New York Times: "I'm fairly confident that we will have another round of indictments.

"We strongly believe there are other people and entities involved in criminal acts."

Mr Weber would not identify the remaining targets of the investigation, or say whether Mr Blatter was among them.

Speaking two days after 14 people were charged over alleged bribes totalling more than $150m (£98m), he dismissed the idea the US government was on a mission to topple the leadership of FIFA.

Mr Weber said: "I don't think there was ever a decision or a declaration that we would go after soccer.

"We were going after corruption.

"One thing led to another, led to another and another."

Federal authorities told the newspaper the timing of the indictments had nothing to do with the presidential election and was not an attempt to damage the re-election changes of Mr Blatter.

However, agents thought it was better to wait until FIFA officials gathered in Switzerland for the organisation's congress to make it easier to arrest people from around the world, according to the report.

An IRS spokesman confirmed Mr Weber made the remarks and said the case is "open and ongoing".

After his victory over Prince Ali bin al Hussein of Jordan was confirmed, Mr Blatter insisted he would begin work to improve FIFA's image immediately after the "tragic events" of the previous few days.

Mr Blatter is due to address FIFA's executive committee this morning, where he will outline how he plans to do this.

But many within the game still think Mr Blatter should go.

Football Association chairman Greg Dyke warned "this isn't over" after the presidential election result was revealed, adding he could not see FIFA reforming itself under Mr Blatter's leadership.

Former Portugal international Luis Figo, who withdrew his candidacy last week, said it was a "dark day" for football and called on Mr Blatter to resign in the next few days.

The head of European football's governing body, Michel Platini, also reiterated his desire for change within FIFA.

Before the result, Mr Platini warned UEFA could boycott FIFA competitions if Mr Blatter was to stay.

Mr Dyke said before the vote he backed the idea of a co-ordinated boycott of the World Cup.

Mr Blatter's fate could yet depend on the reaction of FIFA's major sponsors.

Key sponsor Coca-Cola called for quick, "concrete" reform and action after the vote, joining major sponsors such as McDonald's, Visa and Hyundai who have expressed concern.
