The Gunners have scouted Yazici in Turkey's last two internationals.
The 21-year-old featured in the 2-1 win over Iran and the 2-2 draw with Tunisia this week. Trabzonspor rate Yazici in the €20m class.
“Yusuf wants a move to Europe, Erkut Sogut has been in talks with clubs and there is interest from the Premier League, Arsenal boss Arsene Wenger watched Yusuf in person," said agent Sogut's partner, Ahmet Cebeci, earlier this season. Interestingly, Sogut is also part of Mesut Ozil's management team.
