Just remember that most of City players have good chance to score, so it wouldn't be a big issue if the Inter defenders can mark Haaland tightly. Gündoğan is the most underrated City player but he able to scored important goals. Grealish and Bernardo are fast, and Rodri is tough as well. The problem is their defense, so I expect both team to score in this finale.
I totally agree on that. Marking Haaland isn't the only thing that Inter defender needs to do. Gundogan, Silva and De Bruyne can really become troubles for Inter. I like the way that Guardiola has given the license to Gundogan to go inside the box and try the shots. Earlier it used to be only De Bruyne but now we see Gundogan very often leaping on those chances. Secondly the wingers like Grealish who is very fast and can create space for himself and try to find Haaland inside with crosses and from right wing there is Mahrez who we have seen can also try some good curling shots from the right hand side is also something that Inter defense needs to note down.
If you ask me a solution for Man City, then I would say Inter need immense work rate from each of their player, their responsibilities, roles in order to keep City's attack at bay.
This is what makes it so hard to stop Manchester City at the moment. As soon as they are doing a great job stopping Haaland from making his moves, there are also all these players from the midfield lines who can also score from literally every thinkable position. Since they now recently scored so many goals in the Champions League and in the FA Cup, Inter now had to realize in their analysis how hard it will be to be everywhere all the time during the game. Guardiola has an admirable squad as almost every part of that squad is an option regarding goal scoring. It is close to impossible to defend that for a full 90 minutes and maybe even more than that. Inter will have no chance but to also rely on their qualities to score a goal themselves.
