Last three games in a row since knock out round, Chelsea have conceded two goals and success made clean sheet when eliminating Fluminense at semifinal round, believing with Chelsea if can play fully defense tactical have chance for winning the match and huge pressure for the early minutes if won't conceded goals from PSG as usually scoring goals every early minutes.
PSG's statistics are more than Chelsea's. If Chelsea during the FIFA Club World Cup has conceded 5 goals and scored 13 goals, then all the numbers conceded and scored are far behind PSG's goal statistics.
PSG during this tournament has scored 15 goals with an average goal per game better than Chelsea.
What I am worried about from Chelsea is not their ability to score goals in the final, but the ability of Chelsea's defense to withstand PSG's creative attack.
One way for Chelsea to survive PSG's attacking prowess is to score first against PSG.
