UEFA vice-president Zbigniew Boniek has blasted FIFA's proposal to hold a World Cup every two years, describing the idea as being from "the mentally ill".

The plans to have a major international tournament every year have been met with strong opposition from UEFA, with former Poland international the latest to speak up in criticism of the concept.

Boniek feels that holding tournaments so frequently would congest the football calendar in an unmanageable way.

"Where does this [biennial World Cup proposal] come from? From a home of the mentally ill: it does not exist," Boniek said.

"If you do it, there is no room for other competitions and then you can no longer do the qualifiers, so the national teams must dissolve."

Boniek was also asked about the controversial European Super League concept, which threatened the future of the Champions League.

He added: "Super League? Today it is the Champions League: if they want to make the Super League it is because they do not manage money.

"They want money to manage among themselves and not divide it. 

"Today the money that the Champions League collects is equal to or higher than that of the Super League, the only difference is that it must be divided among the whole world of football. 

"If you make a competition without sporting merit [like the Super League], I don't look at it anymore."
