Liverpool manager Rafael Benitez is the latest high profile figure to criticise the proposal to play a round of Premier League fixtures outside England.
The Premier League announced last week it was considering plans to extend the season to 39 games with the extra matches taking place in five cities overseas, starting in 2011.
But the idea has met with resistance from football federations in Asia and Australia, as well as FIFA president Sepp Blatter, who said he would block the plan.
Benitez has become the first coach to speak out against the proposals.
“I don’t like it,” the Spaniard told The Times.
“I think to play another game in another country is not right for this competition.
“You must play here in England with the same opportunities for everyone.
“I’ve talked to Rick Parry about it and we think the idea is not the best.”
The draft proposal, which all 20 Premier League clubs have agreed to study, could see the top-five teams from the previous season seeded to avoid one another.
Benitez, whose side would be expected to be one of those seeds, dismissed the plan as unfair.
“The seeding idea is the reason I don’t like it,” he said. “It’s important to give everyone the same opportunities.
“If it’s just about money, you can organise a tournament in Hong Kong with the top four if you want and you’ll have the money that you want, but to change the competition in this way is not fair.
“It’s not a good idea and I don’t think it’s a solution for anyone.”
