There has been widespread opposition to the controversial £305million takeover which was completed last month, and the Daily Mail reports that Premier League clubs will refuse to do business with Newcastle in a bid to get the Magpies relegated to the Championship.
The Tyneside club are still winless after nine games following a 1-1 draw with Crystal Palace on Saturday, and the Eagles fans voiced their displeasure against Newcastle's new regime by unveiling a gory banner at Selhurst Park.
Several Premier League players have been linked with a move to St James' Park since the takeover was confirmed, with Jesse Lingard, James Tarkowski and Raheem Sterling among numerous names that have been mentioned.
New director Amanda Staveley owns a 10 per cent stake herself, but is also the face of the consortium. This news will be a huge setback in her claims to bring 'world-class' arrivals to Tyneside.
She highlighted the huge job that lies ahead in improving the overall infrastructure around the club following years of stagnation under previous owner Mike Ashley.
"The training ground is really awful and needs a huge amount of investment," in quotes published by the Daily Express.
"Luckily, that is one area we are not restricted by Financial Fair Play. There is no point in having fantastic players if there is nowhere for them to train.
"We are in the market to compete for world-class players. But if you don't put the infrastructure around that world-class player, you'll get nowhere.
"To me, Newcastle is like a fantastic gem - it just needs a bit of buffing up at every level.
"To get to the top of the Premier League you need a strong foundation, not just great players. They need to be robust and we need to build them.
"We also want to invest in St James' Park - it needs a little bit more love."
The Magpies are also currently on the lookout for a new manager following the confirmation of Steve Bruce's departure last week.
Graeme Jones is in interim charge of the side, and currently leads the club's quest for a first Premier League win of the season when they welcome title-chasing Chelsea to St James' Park on Saturday.
