Manchester City boss Pep Guardiola has questioned Liverpool's Financial Fair Play work.
The club's dealings with sponsors based in their owners' homeland of Abu Dhabi have been the subject of significant scrutiny. City's agreement with the Etihad airline is thought to be worth £67.5m a year.
Liverpool have an £80m-a-year deal with Standard Chartered, while United last March signed a £235m, five-year contract with TeamViewer.
"I've said I'm not going to change that [perception]," said Guardiola.
"When we put here [on the front of our shirts] Etihad, people say, 'Oh it's overpaid'. But now United and Liverpool are going to get paid maybe more than us, because maybe (it's) deserved because they are working well, because the CEO negotiated well, whatever happened.
"They get more and because it's from the United States of America or another country – or the owners are – so now it's perfect."
