Gyökeres has made it abundantly clear that he has no desire to return to Sporting, having refused to report for pre-season, while Sporting president Frederico Varandas has insisted he is happy to fine Gyökeres and keep him at the club if Arsenal do not meet their demands.

Negotiations between Arsenal and Portuguese side Sporting CP have progressed significantly in recent days, with the Gunners increasing their fixed offer to €63.5 million (£54m/$69m), plus €10 million (£8m/$11m) in performance-related bonuses.

Arsenal have reportedly hit a minor snag in negotiations with Sporting Lisbon over the signing of Viktor Gyokeres. It has been widely reported that the two clubs have reached an agreement in principle over a £55.1m transfer that will see the Swedish striker move to the Emirates this summer.
