Sky Sports understands that a delegation from Newcastle United have arrived in Holland to open talks with FC Twente over Luuk de Jong and Douglas.
Newcastle have already seen one bid of €10million (£8million) for de Jong rejected by Twente and they have now reported to upped that to €12million (£10milion).
However, sources close to the deal have confirmed to Sky Sports that Twente are standing firm over de Jong and want in excess of €15million for the Dutch international striker.
Despite their stance, Newcastle have dispatched a delegation of managing Derek Lambias and secretary Lee Charnley to Holland to open talks with the Eredivisie club with the hope of striking a deal.
De Jong is their main point of interest, but it is also believed they will continue talks over Brazilian-born defender Douglas, who has been on their radar for a number of months.
Newcastle are pushing hard for De Jong with German side Borussia Monchengladbach also very keen, although reports suggesting they have already sealed a deal have been dismissed by Twente.
