However, if Chelsea is brave enough to play an open game, then it will make everything easy for PSG to get their win, because even though Chelsea's attack line has improved, but their back line has not, and playing aggressively will make them even more vulnerable.
Not only playing openly but Chelsea must be able to compensate for PSG aggressive play, especially in terms of ball control. Because throughout PSG appearance they really put pressure that overwhelmed the opponent. Example Real Madrid felt how difficult it was to get out of PSG pressure, some moments forced Courtois to make a long pass and the ball led unclear. So Chelsea are challenged to be able to anticipate a game like this.
