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.

The Gunners remain calm over Gyokeres but are growing frustrated with Sporting’s refusal to compromise, as talks over a summer move continue to stall.
