Gyokeres meanwhile has seen multiple drastic twists and turns take place regarding his future in Portugal. The first of those arrived earlier this month when Sporting president Frederico Varandas revealed there was no gentleman's agreement allowing him to leave for £60million (€70m).

Viktor Gyokeres could be set for a Premier League transfer, with Arsenal and Manchester United both keen, and one of his Sporting CP team-mates has spoken out.

Sesko to Arsenal is one of the biggest and longest-running transfer sagas of the summer so far with the window now back open for business, having been linked with a high-profile switch to north London for more than a year.
