Top-flight clubs have complained to the Premier League after it cleared the £305m takeover of Newcastle by a Saudi Arabian-backed group.
There is understood to be frustration from clubs about how the deal passed the owners' and directors' test.
Concerns also arose as to why they were not kept informed after the surprise news emerged on Wednesday.
Additionally, there are worries as to how Saudi Arabian owners will reflect on the league itself.
There are many human rights issues linked to the kingdom.
Clubs are demanding a meeting with the Premier League, which has previously said the takeover process would remain confidential.
