Premier League chief executive Richard Scudamore insists all 20 top-flight clubs still support the proposal to play matches abroad.
The proposal has come in for criticism from a number of parties, but Scudamore insists all the clubs remain behind the idea.
He told Sky Sports: "My shoulders are fairly broad. You take this job knowing it's always going to be an easy ride.
"You work for the 20 clubs. Most importantly you have to work from your base that surrounds you and is closest to you.
"It's important we have the support of the 20 clubs and we still have the support of the 20 clubs to investigate and look at the proposal and bring it back.
"The media have tried to make up some idea that people are breaking ranks, but everyone is in the same position.
"They want to know answers to some questions. They want to think through some of the implications for the competition. They want to know whether the whole thing stacks up and that's exactly where we are, so the clubs are solid.
"We had a good meeting on Tuesday at the professional game board of the Football Association where we explained some more details to our Football League and FA colleagues.
"Because it's the start of the consultation process our professional game colleagues, both Football League and Premier League, were enthusiastic and could see the merits in the proposal, but like all of us need a lot more work to be done."
