Arsenal are reportedly interested in signing Gelson Martins as the winger attempts to terminate his contract with Sporting Lisbon.
According to Sky Sports News, the Gunners are not alone in their pursuit of the Portugal international, who could be available for free this summer.
The 23-year-old's current deal with Sporting runs to 2022 but, along with three others, he is attempting to void his contract, citing "just cause" after the squad were attacked at the club's training ground last month, the report added.
Portuguese football writer Jan Hagen provided further context:
