Inter Milan aren't really an attacking team, of course they have their own way of approaching games and getting goals, but they are not the kind of team that holds possession and attacks constantly, they do not have the necessary quality in their squad to do that. Having said that, there's no doubt that Inter would park the bus against City, even most of the best clubs in the world would do that, when you come up against City you have to respect them and accept the fact that they would control most aspects of the game, Inter have to do one thing, defend and wait to hurt City on the counter.
I agree with you Inter Milan may not be well know for a team that like parking bus but playing against one of the best and most informed team in the world right now which is Manchester City, they will do nothing but reduce in attack and focus more on the defense else they will have themselves to blame because City will run them down. I think Manchester City will have total control of the midfield, possession and ball control but Inter Milan will capitalize on getting a goal through a counter attack then park the bus because City will focus on attack so if they fail to defend after launching an attack that will be a good opportunity for Inter Milan to penetrate them a score.
Manchester City forward has been the main focus of teams they have met from Quater final and Semi Final and I tell you what, other clubs are more focus on their center forward, I hope other teams will not do the same, they should focus on the mistakes they made and improve on their match, perhaps this time they will get Manchester City this one time and win the Champions League, I feel they need more need to study that because that was what Bayern Munich did and the same with Real Madrid, but they always find their way out of the loop and score goal, Haaland shouldn't be their only problem, maybe if they spray across every player, it will work this time.
There is another strategy apart from that, Manchester City becomes dominant of the field as soon as they score, I think if Inter were to able to have a starting goal to lead Manchester City, maybe it will help them stay ahead of Manchester City throughout the match.
