FIFA on Tuesday announced it had filed a criminal complaint against former president Sepp Blatter over the finances of its loss-making museum in Zurich. In a statement FIFA said it had “lodged a criminal complaint with Zurich’s cantonal prosecutor as evidence of suspected criminal mismanagement by FIFA’s former management and companies appointed by them in relation to the (museum) has surfaced.”

Blatter’s lawyer, Lorenz Erni, told AFP “the accusations are unfounded” and vehemently denied wrongdoing.

According to FIFA, the museum generated a bill of 500 million Swiss francs (462 million euros) that instead “could and should have been channeled into the development of global football”.

“We came to the conclusion that we had no choice other than to report the case to state prosecutors, not least because the current management of FIFA also has fiduciary responsibilities to the organisation and we intend to live up to them, even if those before us dismally failed to,” said FIFA deputy secretary general Alasdair Bell.

The Zurich-based museum, a landmark Blatter project, was opened in February 2016 by current FIFA president Gianni Infantino just after he was elected as the successor to the disgraced Blatter.

Blatter was suspended from football for six years over a two million Swiss franc payment to then UEFA boss Michel Platini.

FIFA invested 140 million Swiss frans (130.5 million euros, $138.6 million) in the museum, which is spread over three floors and 3000 m2.

However, it lost $50 million in its first year of operating and attracted an average of 11,000 visitors a month, barely half the target.
