At home, PSG had a smooth start in the group of death in the Champions League when they won convincingly against Dortmund. Determined to succeed, PSG rushed to attack right at the beginning of the match, putting pressure on Dortmund's goal. Mbappé successfully took the penalty kick even though goalkeeper Kobel guessed the right direction.
This penalty helped Mbappe to open the match for PSG and they got a first win in Champions League. This win is a refresh for PSG after a bad streak in Ligue 1 and Mbappe would feel better a little bit. He can feel more satisfied that his goal eventually is helpful and enough for PSG to win a match. Generally, Mbappe will be a key player for PSg in this season and pressure on his shoulders is huge.
Next, Hakimi sealed a 2-0 victory for PSG. The final score could hardly have been 2-0 without missing at least 2 favorable situations at the end of the match. Along with that, Goncalo Ramos was also denied a goal due to offside.
This is the motivation for PSG to aim for the ambition of raising the Champions League championship.
Winning Dortmund is a first match in this season and it is important for PSG to go through this group but to win Champions League, it is another story. They even have yet gotten a ticket for round of 16 and still have 5 more matches in this group to get that ticket. Since knock out phase, PSG will face with bigger opponents and more pressure to succeed, if they are there.
