Arsenal and Manchester United have been handed a boost in their pursuit of Viktor Gyokeres, with Sporting Lisbon reportedly willing to accept add-ons as part of a deal for the prolific Swedish striker.
Sporting have been holding out for a fee in the region of €80million (£69m) for Gyokeres, who has scored 97 goals in 102 games over the past two club seasons.
But the Portuguese champions could now be open to payment structures that include realistic bonuses to reach that figure.
The news comes as Arsenal and United look to strengthen their attacking options this summer, with both clubs long-term admirers of the 27-year-old, who has a release clause of around €100m (£86m) in his Sporting contract.
