Tony Mowbray is open to the possibility of an Atlantic League involving the Old Firm, but has questioned the logistics of the competition.
It has been mooted that the Old Firm could join an Atlantic league, which has received backing from the likes of Feyenoord, PSV, Anderlecht, Brondby and AIK Stockholm.
The Celtic manager has questioned what would happen to Europe's current Cup competitions if the league eventually came to fruition.
Mowbray doubts whether the tournaments could run alongside each other and wants the club to pay close attention to what Fifa and Uefa have to comment on the debate.
"If there is a European league, what happens to the Europa League and what happens to the Champions League?" he said.
"Are they getting revamped? Are they disappearing? Are they running alongside it?
"Could you have a European league and be playing in the Europa League or the Champions League as well? Probably not.
"There is a lot of talking to be done and we will wait and see.
"Our football club should sit and listen to what the bureaucrats come up with, the people who are going to make these decisions, the people at Uefa and others who might be canvassing down south and abroad, and see what develops."
Meanwhile, Mowbray is hopeful a pain-killing injection will enable Scott Brown to feature against Motherwell.
The ex-West Brom boss is pleased Brown missed out on Scotland's trip to Japan as that would almost certainly have ruled him out against Well.
"He's got an injection in a long-running problem that he's had with his ankle and it seems to have alleviated the discomfort a little bit.
"Primarily, he needed some rest. He had been playing two or three games a week since the season kicked off. The boy needed a break basically.
"From our perspective, thankfully the specialist in London agreed with that and he has taken the rest for the last 10 days or so.
"He hasn't put his boots on since we left the field at Ibrox. He has basically been doing as we hoped - resting and giving his ankle time to recover."
Long two weeks
Finally, Mowbray is pleased the international break is over after being forced to dwell on their last result, a disappointing 2-1 defeat to Rangers.
The Bhoys boss is pleased his troops continue to lead the way in the SPL and hopes they can stay there from now until next summer.
"It's been a long two weeks on the back of the Ibrox game," he said.
"But you look at the table as it's printed on paper and as it runs across television screens and you see Celtic at the top.
"The plan would be to keep us there as long as we can, if not right through the season.
"To do that, you have to win football matches and that's the aim this weekend.
"There were positives from the Old Firm game and the result was the major negative.
"I think the performance over the 90 minutes gave us confidence and belief that, if we carry on in a similar vein, we won't be too far away this year."
