Gyokeres was reportedly promised last summer he would able to leave Sporting for less than his €100m (£85m) release clause whenever he decided to move on. A fee of €60m (£50m) up front with €10m (£8.5m) in add-ons had been agreed with the 27-year-old as an acceptable fee which would allow him to leave, but the Portuguese champions appear to have reneged on that deal and are now asking for €80m. The decision does not appear to have gone down well with Gyokeres, who responded by removing Sporting from his Instagram bio.
