However, the Portuguese giants are now demanding €70m (£60m/$82m) as the fixed amount and the remaining €10m (£9m/$12m) in add-ons. If Sporting stick to their stance, there is a good chance that Arsenal will ultimately end their pursuit of the 27-year-old forward.

A deal for the 27-year-old striker is not done as discussions continue over the fee — but the situation is progressing towards a conclusion.

The Gunners are in advanced talks to sign Viktor Gyokeres and remain confident of securing key contract renewals behind the scenes, despite interest from rival clubs.
