Gyokeres' agent Hasan Cetinkaya had a 'gentleman's agreement' with Varandas to sell the player below €100 million (£86m/118m). The agreement was reached at €70m (£60m/$82m) which could be split into €60m in fixed fees with €10m in add-ons. Now Varandas' refusal to sell the player at the agreed fee has left Gyokeres furious.
With his contract running until 2028, Varandas suggested he could end up staying at the club, saying: "Sporting does not need to sell him, but we remain sensitive to the dreams of Viktor and any of our athletes."
