yes, they are very difficult to overcome, when the defense will probably be very focused on Haaland's aggressiveness, but the three of them are very strong behind Haaland. they could even get the chance to score from the second line when Haaland was guarded so tightly.
Inter seems to have to make a double defense and play more defensively in this final match to be able to withstand the attack power of Man City. but in the final match of course everyone will do their best.
