Newcastle have been transformed overnight following the arrival of new owners backed by the Saudi Arabia Public Investment Fund, who replaced the deeply unpopular former custodian Mike Ashley.
Backed by the sovereign wealth fund of the Saudis, Newcastle are expected to be on the path to becoming one of the big boys of the Premier League, but Brazil believes it will take some time.
He does not expect Newcastle to go on a spending spree just yet and it will take a while for them to develop the academy and convince the top players to go and live in the north east of England.
However, the former Scotland star conceded that Tottenham and Arsenal will need to get their act together as Newcastle will be a threat to them now given their newfound spending power.
Brazil said on talkSPORT: “It is going to take a while as far as I am concerned.
“You can’t just suddenly go and spend a billion quid, you can’t.
“Academies, getting the right players in, getting the right managers in and getting people away from London and Manchester to live in Newcastle.
“Don’t forget Arsenal and Tottenham, they will have to up their game now.
“Then there is Everton with Mr Usmanov, he has got billions.
“Tottenham and Arsenal have to be so careful.”
Steve Bruce is now in line to be sacked and there are suggestions that it could happen before Tottenham visit St. James’ Park a week from Sunday.
