The media would be in a frenzy if Chelsea surprised everyone by winning the final against PSG. Everyone seems pretty confident that PSG will win the Club World Cup. So, most of us would be surprised if Chelsea managed to break through PSG's defense. Even if Chelsea loses but manages to score against PSG, they will still be considered a team that has improved significantly. Bayern and Real Madrid couldn't even break through PSG's defense.
