I have a different view, when you say PSG v Madrid match there will probably be a lot of goals scored but to me it doesn't look like it will happen. I personally expect the match to be tough so both of them might be deadlocked to score goals but yeah, I think everyone has their own version of how many goals it can be said to be a lot of goals. Because if it's just two goals though for both teams, surely it's a meager amount of goals even though both teams are to score.
This game - PSG vs Real Madrid - is one of those games where you can see a lot of goals or a few goals. If the teams are extremely organized and manage to cancel each other out, then we will have few goals. If the teams play very open, both focused on attacking, we can see several goals from both teams. It can also happen that a team starts to stand out right at the beginning of the game and score early, and then the other team, wanting to recover, end up suffering more goals.
But in my opinion, maybe the match will only produce a little goals later, because the two teams have a squad depth that is quite capable and evenly distributed in each position, besides that individual and collective abilities as a team are also owned by both teams, so of course in that match both teams will playing with carefull and minimizing any mistakes that might occur, I think the PSG and Madrid match will put the maturity of the squad and also the winning mentality.
