Leeds United have reportedly tabled a second bid for Brighton centre-back Haydon Roberts.
Last season's Championship winners submitted an offer for the teenager last week, an approach which was firmly knocked by the Seagulls.
Brighton's rejection of Leeds' bid hasn't put off Bielsa, who, according to Football Insider, has tabled a fresh £800,000 offer for the 18-year-old.
Bielsa is said to be a big fan of the England youth international, who has drawn comparisons to former Leeds loanee Ben White.
Leeds aren't the only club to hold an interest in signing Roberts this month, with Championship outfits Derby County and Brentford also said to be interested in acquiring his services.
Roberts recently entered the last year of his contract at the Amex Stadium, although it's currently unclear if Brighton wish to keep him on their books or if they're eager to cash in on him.
Should Leeds have their second approach for Roberts rejected, they could very well table a third offer for the defender.
Leeds picked up their first win of the new season last Saturday, beating last season's Championship play-off final winner's Fulham 4-3 at Elland Road.

Bielsa was over the moon to have got three points on the board but admits he's concerned by the number of goals his side is shipping.
He said: "It was a game where we couldn't really show ourselves. In the first half, we defended better but we didn't really create much danger.
"In the second half we attacked a bit better but we didn't finish attacks very well. Finally, we were able to impose our game a little bit."
He added: "There's no particular motive for us being so efficient at the moment.
"Normally we are a team who need a lot of chances to score goals, at the moment the opposite is happening. I don't think there's anything definitive behind this.
"We've only played two games. Nothing that happens can be called a tendency at the moment. We will have to wait a few more games before we can start making conclusions."
Bielsa's troops will be back in action on Sunday afternoon, travelling to Bramall Lane to take on Sheffield United.
