The Kingdom of Saudi Arabia's (KSA) Public Investment Fund (PIF) are reportedly targeting a move for Diogo Costa for Newcastle United in January.

The Lowdown: Dubravka's exit

Martin Dubravka completed his loan move to Manchester United on transfer deadline day, meaning that the Magpies now have three senior goalkeepers in their squad.

If they were to bring in another man between the sticks, either Karl Darlow or Mark Gillespie would be the likeliest to depart, as Nick Pope has established himself as the new number one following his move from Burnley.

The Latest: Costa targeted

As per Jornal Do Noticias (via Sport Witness), Costa is a 'tempting target' for Newcastle in January, having sent 'emissaries' to watch him play for the Portuguese national team in June.

He has a release clause of €60m (£51.9m) but is currently valued closer to €25m (£21.6m), so the kind of transfer fee required to sign him would likely fall somewhere in between those two figures.

The Verdict: Unlikely

Given the signing of Pope, who has started well on Tyneside with three clean sheets and just six goals conceded in his opening six Premier League games (Transfermarkt), it seems highly unlikely that Eddie Howe's side would spend that much on Costa, who would not be guaranteed to start.

Hailed as ‘superb’ by journalist Zach Lowy, the 6 foot 2 colossus helped Porto to win their domestic league title last season, with an impressive 15 clean sheets in 33 matches and just 22 goals conceded in the Portuguese top flight (Transfermarkt).

Costa is no doubt a fine goalkeeper already at just 22 years of age, but with Pope already at St James' Park, it would seem strange that the Magpies would go for another established stopper.
