Real Madrid won by a big margin in the first match of the Champions League. Real Madrid's opponent in the first match was VfB Stuttgart. Real Madrid won 3-0 against VfB Stuttgart. Mbappe scored the team's first goal in the 46th minute but VfB Stuttgart equalized later on, but late on brilliant finishes from both Brazilian strikers ensured Real Madrid won by a wide margin. Both teams managed to score a total of four goals in the full time, but all of these four goals came in the second half. This is not new for Real Madrid, in many matches they are behind by a big margin but they paid for that goal in the second half and won. Congratulations to the beloved team Real Madrid.
The score was 3-1, not 3-0 for Real Madrid.
I've just watched the extended highlights of the game and frankly, despite the result, Stuttgart looked like a better team. They absolutely dominated the first half, they had a lot of great chances to score but were just out of luck.
The second half was more even and it was Real who came on the top, but we have to give Stuttgart a due credit. They played a really good football, dominated in ball possession and created better chances. If they keep playing like this, they could turn out to be a dark horse of this season UCL.
An important rule in football says: you must learn to take your chances when you have them, or you will get punished. I agree with you that Stuttgart played a very good football. At some point, I thought it was going to end in a draw, but Rmadrid wasn't going to let that happen. Rmadrid's performance this season hasn't impressed me much. I don't really know what's going on with them. I hope they are not planning on using the same approach where they play poorly from the beginning of a season, and ends the season in a a very fine form. Or maybe they are just trying to adapt to every game. I will be looking forward to watching their game against Liverpool. Maybe that will allow me rate their form this season.
PSG can cope without their first choice goal keeper in their match against Girona. Provided that the squad are playing very good and their back up goal keeper is fit to start for them. Provided that the defense is well composed and are not allowing the Girona players to penetrate them that much. Moreover Girona are just new to the Champions league and lacks the experience of the Champions league, so they shouldn't be much of a trouble for PSG to see them off.
I feel PSG playing without donnarumma who happens to be their first choice GK is a big blow to them. This is UCL. I definitely expect goals from both sides, because you don't expect a side to be 100% good on both attack and defense. Girona will surely have their chances, and I believe they will take them. But, PSG might just be taking all 3 points, seeing that they already have the UCL experience, and also quality players among them.
