Brennan Johnson is set to hold talks with Crystal Palace boss Oliver Glasner on Thursday before reaching a final verdict on whether to seal a £35m switch from Tottenham.
BBC Sport understands there is increasing confidence that the transfer will go through, although the discussions are expected to be decisive in determining whether the move is finalised.
Palace have already struck an agreement with Tottenham over a fee for the 24-year-old attacker but are still awaiting approval from the player before completing the deal.
The Wales international’s meeting with Glasner will focus on his prospective role within the squad, as well as the club’s long-term vision and ambitions, to ensure all sides are on the same page.
Should the talks prove positive, Johnson is anticipated to put pen to paper for Palace in the coming days.
He remains Palace’s top priority for the January transfer window, with the club eager to wrap up the signing at an early stage.
BBC Sport revealed last month that Tottenham were willing to part ways with Johnson, who finished as their top scorer last season with 18 goals.
Despite that individual success — which included netting the decisive goal in Tottenham’s Europa League triumph over Manchester United in Bilbao — Johnson is not viewed as part of manager Thomas Frank’s long-term plans.
