Will the current format be ruined?

The European football organization in December will decide whether to change its current format system or introduce a new one for the Champions league. One of the options is to include guaranteed places for the biggest clubs coming from the strongest leagues and playing games on weekends (Saturday) instead of midweek. Possible change, in the 'strongest' European cup competition is available every three years as the UEFA marketing team can sell broadcasting rights to interested media in the next commercial cycle. And until that cycle will be over in 2018, 32 group phase clubs will share almost 1.3 billion euros each season from UEFA.
