The Kingdom of Saudi Arabia's (KSA) Public Investment Fund (PIF) have sent scouts to watch Moussa Diaby ahead of a potential Newcastle United move.

The Lowdown: Summer interest

The St. James' Park outfit were credited with a serious interest in Diaby during the summer transfer window, but a deal never materialised in the end, with the Bundesliga outfit seemingly determined to keep their star men ahead of their return to the Champions League.

Now, the Magpies could move again for him in January, providing that Leverkusen are then open to a sale.

The Latest: Scouts sent

Writing in his latest piece for 90min, transfer expert Graeme Bailey has revealed that PIF sent Magpies scouts to watch Diaby in action in Leverkusen's 2-0 win at home to Atletico Madrid in midweek.

However, representatives of Tottenham Hotspur, Manchester City, Arsenal and Chelsea were also present, ahead of what could be a big Premier League bidding war for the winger in January.

The Verdict: Get it done

After the signing of Alexander Isak from Real Sociedad, the Toon board would be making another real statement if they ended up signing Diaby.

Hailed as a 'fearless' player with 'electrifying pace' who is 'good with both feet' by The Chronicle journalist Aaron Stokes, the North East club would have liked what they saw from him against Atletico.

Not only did he get himself on the scoresheet, but he also made two key passes and won two of his individual duels (SofaScore), and at 23 years of age, Eddie Howe's side would be signing a player with huge long-term potential.
