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.
No doubt Lukaku has all the qualities of a complete striker, however I think Inter Milan is considering his defensive ability in tracking back to help the midfielders probably help the team to launch counterattack, it's quite difficult for any opponent to dispossessed Lukaku when he is with the ball because of his physical strength which is another another advantage that he can utilize to create space and chances for Lautaro Martinez whose major strength is his pace and strength as well, meanwhile it's obvious Man City will dominate the match in term of possessions it's up to Inter Milan manager to deploy whatever tactic to absorb the pressure and mark very well.
