Leeds United have suffered a major blow in their pursuit of Brenden Aaronson...

What's the word?

After having an initial £15m bid knocked back by RB Salzburg earlier this week, it appears as if the Austrian Bundesliga champions have told the Yorkshire outfit that their star midfielder is absolutely not for sale this month.

That is according to 90min, who claim a club spokesman has told the website that the 21-year-old is not leaving the Red Bull Arena anytime soon.

Perhaps that is hardly a surprise given their involvement in the Champions League knockout stages, where they will face German giants Bayern Munich later this month.

Gutting blow for Bielsa

This will come as hugely gutting news to Marcelo Bielsa, who is said to hugely admire a player of Aaronson's quality and potential.

He is not only thought to be Leeds' only target during the January transfer window but also one that the Argentinian head coach has personally demanded.

"So, Brenden Aaronson's the one Leeds United want. The top and only target right now. Another offer will go in," revealed LeedsLive reporter Beren Cross earlier in the week.

Meanwhile, fellow journalist Pete O'Rourke recently told GIVEMESPORT:

"He's the one that Bielsa really wants. He thinks he fits the profile as the type of player that can go straight into his side."

Indeed, it's easy to see why the 66-year-old wants to bring Aaronson to Elland Road before deadline day in a little over ten days time.

His performances in UEFA's elite competition have been quite remarkable indeed - operating as a 'half-winger' in Salzburg's 4-2-2-2 system, he ranks amongst the top 1% of midfielders for pressures (27.84 per 90) and forcing the opposition into losing possession (8.55 per 90), via FBRef.

That goes to show his immense work rate in the final third and as we know with Bielsa's philosophy at Leeds, he likes his attackers to defend from the front with a high press.

Dubbed "ruthless" and "relentless" by his former Philadelphia Union head coach Jim Curtin, the young "playmaker" would tick plenty of boxes for Leeds.

Aaronson would fit like a glove in the current United squad, so the fact that the Yorkshiremen won't be able to sign him this month will come as a devastating and frustrating blow to Bielsa, who must be livid to not secure his main target.

It's now four years since the club bagged a new midfielder and that wait could rumble on further now.

AND in other news, Bielsa could land the next David Batty in "exciting talent" as Leeds  target "big signing" this January...
