If Inter doesn't attack, then of course Manchester City's defensive line will logically not be too tired, but in this way Manchester City will have many ways to create attacks. So yes, I think it doesn't matter whether Dzeko or Lukaku will be played first because after all, the most important thing is whether Inter can break Manchester City's dominance in the match later. Because, if Inter can't do a lot of attacks too, then Inter's forward players will at least help the defense a lot too right.
Whether Inter Milan or Manchester City, any team that fails to attack and not put pressure on their opponent are given them more time to be able to grasp and use different terminology to break into their defence. We expect to see an intense game tomorrow since it’s the champions league finals. Manchester City are known for counter attacking when they see the chance, Inter Milan’s defence have to be careful and hold grip of their defence to avoid Manchester City’s attackers to keep penetrating them, in that way, we’ll have a more interesting match to watch. Inter attackers are also good and I expect them to also attack when they see any chance at that.
