Newcastle must add to their squad in January with Rafa Benitez likely to be backed.
The Evening Chronicle claim Newcastle are due a "sizeable chunk" of the centralised prize pot in England's top tier, and that is expected to be enough to fund Benitez's transfer dealings in the winter window.
A central midfielder and a striker are likely to be high on Benitez's shortlist, but a left-back should also be one of the Spaniard's priorities with Paul Dummett's hamstring injury highlighting the need for a left-sided defender.
It has seen Ciaran Clark play at left-back away from his natural centre-back position, while Javier Manquillo has also been forced to play on the left side despite being right-footed.
But Benitez should throw his hat into the ring to rival former side Napoli, with Lingenti claiming the former Olympiakos ace would cost nine to 10 million euros, or between £8.2million and £8.9million.
Masuaku has been forced to wait for his chance, with England international Aaron Cresswell preferred to him. However, he has impressed on occasion this season, laying on two assists in his six appearances.
Adding speed, a willingness to get forward but also the intelligence that has come from playing under Cresswell, Masuaku would be the perfect addition to the Toon's squad at a reasonable price.
