Sporting President Frederico Varandas has warned that striker Viktor Gyokeres will be fined and asked to apologise to his squad after failing to turn up for pre-season training on time, amid reports of a move away from the Portuguese club.

Gyokeres, who scored 54 goals last season, has three years left on his Sporting contract and has been linked with a move to the Premier League this summer.

Arsenal are working to land Gyokeres and have a five-year deal prepared, subject to the clubs reaching an agreement over a fee.

Viktor Gyokeres could be on the move this summer to Arsenal and it has now been revealed how the Gunners could eventually pick up the striker for free. The 27-year-old is among one of the transfer sagas of the past few months with intense speculation surrounding his future and where he will be playing his football next season.

ARSENAL have a HUGE summer of business to take care of in the transfer market and have been busy at work. Noni Madueke is set to leave Chelsea’s camp in the US to have a medical at Arsenal,
