There is some activity at Benfica also. Orkun Kökçü is about to leave. Kerem Aktürkoğlu is also speculated to leave this summer. They are both among the most valuable players in the squad now.
As a Benfica fan I think it's good for these two to leave.
They promised more than they actually did. Kokcu always had a slightly rugged attitude, for the real performance he had.
Benfica is a team that can find better replacements for these players. No player is indispensable. While Orkun Kökçü and Kerem Aktürkoğlu are playing well, they are not essential for Benfica. If they leave the team this summer transfer window, Benfica won't be upset; they will strive to acquire the best young players in that area. As one of Portugal's respected teams, Benfica has never had a player shortage.
