La Liga president Javier Tebas has warned Europe's top clubs of the destabilising effect seeking further riches through a revamped Champions League or FIFA's new

Club World Cup will have on national leagues.

China will host FIFA's expanded 24-team Club World Cup in June and July of 2021, while talks are ongoing over plans to reform the Champions League from 2024.

However, Tebas believes increasing revenues must be more evenly redistributed to prevent the increasing dominance of a few select clubs.

Barcelona and Real Madrid have also hit a century of points in La Liga over the past decade.

Juventus have won eight Italian titles in a row, Bayern Munich have been crowned German champions for the past seven years and Paris Saint-Germain have claimed six of the last seven Ligue 1 titles.

"I don't think we are helping football in any way if we generate wealth and it just goes straight back to the big clubs but that's what's happening, the major clubs share out the large part of the income among their players," Tebas told reporters at a launch for La Liga TV in London.

"In the end instead of having 12 Ferraris, they have 15. Instead of having 10 Lamborghinis they have 12. We're dealing with major clubs generating a huge amount of money. So our aim is to redistribute that wealth."

Proposals to change the Champions League to four groups of eight and introduce promotion and relegation to Europe's premier club competition have been rejected, but some reform is still expected in the coming years.

- 'Grassroots won't benefit' -

Meanwhile, FIFA's Club World Cup expansion has already met opposition from top managers with Liverpool's Jurgen Klopp and Pep Guardiola of Manchester City criticising the addition of more matches to an already congested calendar.

However, rather than player welfare, Tebas is concerned the huge prize money offered to clubs to take part in China will cause the gulf between the richest clubs and the rest to grow.

"It's not just about generating more money and creating a legacy, like FIFA is doing with the Club World Cup, for example. Often, the implications, the ramifications, are not considered, and that can cause harm," he added.

"Everything we're talking about new formats and competitions aren't going to benefit grassroots football, they're going to benefit the 10 or 15 major clubs."

For the first time this season all of the Champions League's last 16 will consist of teams from England, Spain, Germany, Italy and France.

And Tebas called for greater distribution of the booming TV revenues from UEFA to prevent the latter stages of the competition becoming a closed shop to teams outside the top five leagues.

"We need to be able to help other leagues and place them in a good situation so they can grow and that means redistributing the wealth generated," he added.

"If we continue to have economic problems in Eastern European leagues or other leagues like the Greek league then in a few years our industry will collapse. We need to strengthen football as a whole."afp
