Dzeko is the last I would mention from their good players :)
They have some very good players like:
Barella, an excellent midfielder very dangerous and good with the ball.
DiMarco, a high paced left back that usually goes full force on the left side to help the offence with a very sweet left foot and many contributions(6 goals, 10 assists this season). He is most probably the best left back in Italy right now. Walker would be needed there and he will need help also, as they overload all the time that side along with Brozovic.
Brozovic a well known very good and dangerous player.
Lautaro Martinez obviously on great form with Inter a very dangerous player in his day. He will play.
Lukaku well I guess you know him well :) It's between him and Dzeko for playing in the final.
Mkhitaryan excellent player, too dynamic, with good technique and dangerous on attack.
Calhanoglu a solid central midfielder but nothing too great.
Dumfries playing on right wing with a great pace is a very dangerous weapon. He is sloppy defensively though.
Onana a solid goalkeeper with a great season.
