Instead, their new manager - whoever that might be - could have the chance to sign the likes of Barcelona superstar Ousmane Dembele, as the new owners look to flex their financial muscles.
Goal are claiming that the Frenchman would be interested in a move to Tyneside, which would be the Newcastle owner's first real statement signing - their 'Robinho to Manchester City', if you will.
Dembele isn't the only Barca player to be linked with the Magpies, however.
Former Liverpool man Phillipe Coutinho has been rumoured to be interesting Newcastle ahead of a potential move in January.
The Brazilian, who could join his countryman Joelinton at St James' Park, scored 41 goals and provided 35 assists in 152 games during his spell on Merseyside.
With both players - who are the Spanish club's two record signings - failing to get consistent game time under Ronald Koeman in Spain, and with Barcelona needing the money due to their poor financial situation, a move could suit all parties.
Burnley's James Tarkowski, Manchester United's Jesse Lingard, and Everton's Dominic Calvert-Lewin are all said to be on the Toon's shortlist too, when the transfer window opens in a few months' time.
Perhaps less flashy than the likes of Dembele and Coutinho, but the trio - who all currently ply their trade in the Premier League - would provide some solidity and know-how to a team that is undeniably in a relegation scrap.
The current crop of Newcastle players, who are used to battling at the bottom end of the division, will still be useful, however, even if they do sign spend big on new players.
The likes of Martin Dubravka, Jamal Lewis, Javi Manquillo, and Isaac Hayden may be given a chance to prove themselves to the new manager before another big spend next summer, as they look to climb the division.
