Yes, we can see how in the end, Chelsea and Tottenham also saw how they found gaps in the game applied by PSG. PSG did win the Champions League last season, but their strength has not yet been dominant.
Every match will be studied by opponents, if they do not make improvements in their performance, they will only get caught in traps set by other teams. PSG is still a strong team, but they must work hard to overcome all their competitors in this season's Champions League. It seems quite difficult for PSG.
PSG won the Champions League because they literally surprised Inter Milan in every way
They used a strategy that nobody expected and deservedly won.
But of course the teams geared up and studied their tactics until they found the weak points. Chelsea for example won against PSG in the Club World Cup final by highlighting PSG's weaknesses
Not only Chelsea, but Tottenham is also studying how Chelsea defeated PSG, even though in the end, they had to lose. We can see how poor Tottenham's performance was last season in the Premier League. They were at the bottom after the relegation zone. Facing PSG because they won the Europa League against United. But they almost won against PSG.
Every match will certainly have a different situation. PSG is clearly favored, and they indeed have the advantage. But Tottenham also did well. Whether Tottenham is better or PSG is declining.
