For the final of FIFA club world cup, odds were heavily in favour of PSG because of factors like their performance in the tournament, strong defence (conceded only one goal before the final). But what Chelsea has done in the final was not in anyone mind. Chelsea finished forth in EPL last season while PSG is not only top team of french league but also current UEFA Champions league winner. Chelsea win has confirmed the fact that quality of football in EPL is one of the best in the world.
Most definitely the quality of EPL football is top notch and obviously number 1 in the world and so a champion from other league may meet an EPL team and get defeated, in this case even if we are aware that as at th time Chelsea was not looking like they were in their best form, PSG had all the favour because they had proven before then that they were just the right team to win the trophy, the quality of Ligue 1 is not anything compared to the EPL and I believe most persons will agree to that but let us also know that sometimes it may not matter, even a relegating team.can beat a champion in some cases, luck does has a role to play.
