Clubs wishing to leave the Super League project face a massive penalty clause.

De Spiegel has released a few pages of the contracts signed, which was agreed to by the Premier League's 'Big Six', as well as three clubs from Italy and three from Spain before the controversial announcement last week.

They include Barcelona and Real Madrid both receiving an extra €60million (£52m) each more than their rivals, the right for each club to exclusively broadcast a number of matches and a £130m fee for those wishing to withdraw from the competition.

It says that clubs who pull out of the Super League face a '£130million' penalty fee, which would be a huge blow to the six Premier League clubs and others who have withdrawn their support.

The leak came after Super League clubs were handed a boost on Friday when UEFA determined they would not hand them sporting punishments.

Manchester United, Manchester City, Chelsea, Tottenham, Arsenal and Liverpool all withdrew their commitment this week.
