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.

Madueke is due a break after playing at the Club World Cup, however Mosquera is set to be part of Arsenal’s tour to Singapore and Hong Kong this month. Arsenal depart for Singapore on Saturday and want to have Gyokeres on the flight out there.
