I think Inter Milan is going to try disabling Haaland for this match because they are aware of his powers and if they don't put Haaland under pressure one opportunity can be enough for him to change the game.
Yes, you’re right. Obviously, they would want to try and guard tightly Haaland who is known and good at suddenly opening up to receive passes/crosses and being able to finish off beautifully. Inter Milan knows he’s a danger man and would try to keep him closely marked at all times.
But I doubt that would make any difference in the game as Manchester City doesn’t depend wholly on the abilities of Haaland as there are other players who, when with the ball are equally dangerous and capable of scoring goals as well. Inter Milan do need to be prepared to face a tough competition.
Most of the assists made by many players this season have gone to Haaland, and by using a simple attacking strategy, Inter will want to make Haaland their focus, but knowing Manchester City, they are always ahead of every team in every match, and I believe they will use that to confuse Inter's players. The fact is, Manchester City don't just have powerful forwards; their defence is also great. This is Inter's difficulty; they will have to play both offensive and defensive games if they want to win this match; Inter will have to put in double effort to win this match.
