According to some speculation, Inter will play Dzeko over Lukaku at the start.
Not sure if it is the correct choice, for sure he has more experience.
Looks like Lukaku was played at mid-time with the aim of providing sharper counterattacks in order to break through the enemy's defense.
But the enemy they will face is Manchester City so any kind of counter-attack will be difficult to break into Manchester City's goal.
The match that they will play is to fight for the title so that Manchester City will really give full strength to the defense position and the forward position for attack.
