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.
Then, what you need to make your team able to break city's defensive line? lukaku was the answer for that. I meant lukaku has everything compared with dzeko. Lukaku does have speed, physical strength, good execution when it must be 1 vs 1 against goal keeper. He is also a good dribbler too. It sounds non sense to put dzeko as favorite striker to be used by intermilan against manchester city. Dzeko was good but when it comes to the speed, dribbling or even strength and i will prefer to take lukaku rather than dzeko at this moment.
It's caused by lukaku can also help its team to give free space for lautaro martinez. It's caused by city will have need more than 1 players to stop lukaku due to the his good physical strength.
He has even better physical strength compared with haaland.
