Samardzic, Akliouche, or other players which the scout have the list based on player strength Motta and Giuntoli needs.
Yes, Koop is productive player but for €60m player CM, risk is very big. Motta and Giuntoli are definitely know what the team need for their system but i see us still lacking for CM that good in final third. Have a good control of the ball, compose, creative and have eye for the goal or assists like Barella, Odegaard, F. Ruiz or a box to box like Valverde
If we compare it with Inter as benchmark because they won the league last season. We can compare Douglas Luiz will play in Calhanoglu role. Kephren Thuram as DM, but we dont have player like Barella
Based on a year stats Koop is not that exceptional in terms of attacking metric, he is more standout in defensive metric which we alresdy covered by Thuram
Compare with Fabian Ruiz who excel in 2/3 third of the table :
Or Barella
Both of Ruiz and Barella is inferior in defensive aspect but superior in attacking part (passing, ball carries, chances creation, shooting chance).
In friendly our problem is scoring goals, that's why we should look for CM with more attacking prowess we need. You can also check other player mentioned above like Valverde. That's why i dont oppose signing Koop but paid extra huge sum for him seems a risk which could be not answer our needs
