Chelsea is surely a much superior team than Fluminense but Fluminense too played a good game against such strong opponent. The game was not one sided and Fluminense did created some good attacks. With this performance and new signings, Chelsea could be a contender for the next Premier League title. But when you compare the English team with Spanish team or the PSG, they fall behind. Whoever be the winner of the next semi finals, finals is going to be tough for Chelsea.
Chelsea won't be a serious contender for the Premier League next season because there are still several other strong teams in the Premier League. As for the final, I also predict Chelsea will face a tough opponent, but whoever PSG or Real Madrid qualifies for this Club World Cup final, it's important not to underestimate Chelsea. Because Chelsea already knows they will face a tough opponent in this Club World Cup final, Chelsea will make more thorough preparations before the final.
