After showing interest in Benjamin Sesko from RB Leipzig, Arsenal has now shifted their focus to Gyokeres. Berta is in Portugal to hold direct talks with Sporting's directors and to discuss the transfer fee.
It is believed that Berta will try to reach a deal worth up to £70 million with Sporting. Gyokeres had previously agreed to join Arsenal on a big contract, worth £200,000 per week.
Gyokeres had a remarkable season with Sporting last year, scoring an impressive 54 goals. His impressive performance has made him a valuable target for many top clubs.
