Curbishley's comments follow ongoing uncertainty surrounding Rafa Benitez's position in charge at Anfield.
Benitez has since played down reports of a rift, and voiced his confidence at staying on as Liverpool boss for at least another year.
And while Curbishley is sure Benitez will remain as Liverpool manager, he is unsure if the growing investment from abroad is having a positive effect on the game.
He told Sky Sports News: "What is happening now - in the atmosphere we have got in the Premier League with new owners appearing every month - is that perhaps they are not really up on the way football is and the traditions, and the way to perhaps conduct yourself.
"I am sure they are learning. A loose comment here and a loose comment there can make a big difference.
"But I think Liverpool do their talking on the pitch. If you look at the club, I know the Premier League has been out of reach but they have won everything else.
"Over the years they have always backed their manager - whoever it may be - and I am sure they are going to back Rafa.
