Keeping Haaland tight will not be enough to silence the Man City attack. Because Man City's forward players actually have almost even skills, that is, they can always endanger the opponent's defense. Even if Inter Milan focuses too much on Haaland, Inter Milan's fate could be the same as what happened to Real Madrid in the semi-finals.
If the Inter Milan defense keeps their focus mainly on Haaland, then I think they would be making a big mistake. They might focus mainly on Haaland and forget other players are equally as dangerous. Manchester City has capable midfielders that could also score goals. Haaland is instrumental in scoring goals as he finishes beautifully but i believe Manchester City could always do without him.
Gundogan and De Bruyne, as well as Grealish are players in my opinion to also watch out for that could cause some problems for Inter Milan.
Well, on this side how the system speaks. the point is, how will Inzaghi implement the system for the defenders. it could be, Inzaghi instructed man to man marking by placing 5 players on the defensive line. because it seems, this system is the most ideal. how come, yep, this pattern is quite in harmony with Inzgahi's 3-5-2 system. that is, 3 defenders will stay in their positions, 2 midfielders will go down to become defenders. The other 3 players will try to low block, leaving 2 forwards. or, 1 player comes down to help the midfield. which in the end, their defensive pattern with 5-3-2. or, can be combined depending on needs. after all, this formation is strong enough to withstand the 3-2-4-1 pattern.
Well, here we will see how the Inter players play disciplinedly, especially their defensive line players. in theory, Inzaghi has a systematic defense. however, the problem is that their opponent is City. if the scenario is as i said, there is 5 vs 5 players facing each other. So, the key is in their line of defense. if the Inter players can cut the ball in midfield or something, they can counterattack quickly. the pattern can change to 4-3-3, or so on depending on Inzgahi's strategy. so, it's not just Haaland who they will mark strictly. for sure, every City player has the potential to score goals. depending on what opportunities they have. and this will be a tough job for Inzgahi in the final match later.
