Man City players will definitely not underestimate Inter Milan. It's just that Man City, who might be playing more carefully, could actually be used by Inter Milan. Man City, which always fits their attack strategy, will certainly trouble Inter Milan's defense. But if it turns out that Man City has reduced the aggressiveness of their attacks, then this will open up opportunities for Inter Milan to be able to turn around to play more attacking. But Inter Milan must also be aware that Man City players' attacks are always dangerous. so Inter Milan might choose to use a defensive strategy in the final match later.
IMO, this match will not be much different from the City vs Madrid match. City will dominate the midfield more, some City players will try to open space for their team-mates. most likely, Haaland and De Bruyne will get tight marking. to anticipate it, it is likely that Inzaghi will put 5 of his players in defense. however, as usual, Pep will instruct Haaland to open up space for the rest of his team-mates. so, don't be surprised if the City players will try to provoke the Inter players with shots outside the penalty box. thus, the concentration of the system that Inzaghi applies to his line of defense will loosen up a bit.
If this scenario occurs, several City players will have the chance to score the first goal. after that, the fight will start to open up a bit and get more exciting. because, Inter will be slightly out to equalize. yes, once again I say, the scenario will be the same as during the City vs Madrid match.
by the way, this is just my assumption and does not determine what will happen when this fight is held. it's just that, I would still choose City to bet but with other options because the odds available are not ideal.
