Guardiola tackled the issue head on, confirming he only found out of the developments on Sunday and rebuked ringleaders for a lack of clarity.
"It is not a sport where the relation between effort and success does not exist," he said. "It is not a sport where success is already guaranteed or it doesn't matter where you lose.
"It is not fair when one team fight, fight, fight at the top and cannot be qualified because it is just for a few teams.
"The right people have the obligation, the duty, to clarify as soon as possible, clarify all around the world why these teams play and the others not. Ajax - with four Champions Leagues - why they are not there?
"Everyone makes (decisions for their) own interest. The Premier League looks at his interest, UEFA looks at his. To arrive in that point, Uefa have failed. They have to communicate and be in touch before."
