Newcastle's newfound riches have seen them linked to a whole host of players.
Newcastle United's seismic lack of goals this season means that they will likely be in for a striker come the January transfer window - and if reports are to be believed, Real Madrid striker Mariano may be that man.
Mariano, 28, was brought up in various youth academies in Catalonia before being introduced to the Real Madrid set up at the age of 18.
Having played for the C and B teams of Los Blancos until he turned 23, the striker was brought into the first team and impressed in his first season, scoring five goals in 14 games.
Lyon came calling for a fee of £7.2million, and the Dominican Republic International shone in eastern France, scoring 21 goals in just 45 games at the Groupama Stadium.
Real decided to amend their previous mistake and buy him back for a fee of £33m, but like a lot of transfers at the Santiago Bernabeu, this one has flopped.
But the talent is still there, and Newcastle fans will be hoping that a potential deal for Diaz could happen.
A report from Cadenar Ser says that Newcastle are expected to make a bid for the striker.
A fee of just £8.2m (€10m) would be enough to bring Mariano to St James' Park, if their report is to be believed.
"With this offer, it’s certain that Real Madrid do not think, that they’d be delighted," say Cadenar Ser.
And having played no games so far this season, it would make sense for Carlo Ancelotti's men to take any fee whatsoever in their bid to shun him from the wage bill.
