Dortmund also has long experience in the Champions League. But I also considered how AC Milan was also able to qualify for the round of 16 last season. Even last season, AC Milan performed very poorly in Serie A. But at that time, AC Milan still managed to go further in the Champions League.
So the Dortmund vs Milan match will definitely be more difficult for us to predict. But because the match will take place at the San Siro, maybe Ac Milan really deserves to be the favorite. But currently AC Milan also has several core players who are injured. So I doubt whether Milan will succeed in getting full points or not. But I'm sure Milan will not lose as hosts. What I still doubt is whether Milan will get 1 point or will get 3 points.
If Milan would not lose as the host team, the game will end in a draw or a win for the team. Borussia Dortmund is hardly a weak team that Milan will be confident of defeating. If they need three points to boost their chances of winning, they must be particularly prepared to face a strong team like Borussia Dortmund, which has been performing exceptionally well in the Champions League competition. Playing at home does not guarantee that they will win the match against Borussia Dortmund; it will just offer them additional confidence and applause from fans. They must demonstrate their skills in order to advance to the next stage of the competition.
PSG no longer have Messi and Neymar but they still have many star players in the club. Star players are not players above average quality but they have higher quality than that. They have a quality coach who have semi final in Euro 2020 with Spain and won Champions League, La Liga with Barcelona.
It makes no difference whether there is Neymar and Messi or not because at the time they were still playing for PSG but were also unable to win the Champions League title. Currently PSG has a much more stable squad and also has a much better coach than before. Luis Enrique needs time to build a more solid team and if management can be patient then I am sure he will be successful at PSG.
Being good as a team and winning trophies is dependent not only on the number of good players in your squad, but also on how the manager manages and coordinates these players in every match so that they always win. PSG acquired one of the top quality players at the time, but despite using them in all competitions, they were eliminated from the Champions League. PSG are still OK in my opinion; they simply need stronger management, which I am confident their new coach, Luis Enrique, will be able to provide as the club's new manager.
