You're right the odd given to flaminense is not a true reflection how good flaminense is so anyone who can take the risk should try and bet on flaminense because this game is a 50/50 game I don't see Chelsea as that fantastic to the point of giving 5.72 odds to flaminense let see how this game will go a expect a close one from this game
In this tournament, I wouldn't say Chelsea have been impressive. They're just lucky to have gotten this far because of their features. I watched Fluminense against Inter Milan, and they put up a very solid performance. They may seem like the underdog, and many punters will be betting on Chelsea tonight, but Fluminense can stun everyone by beating Chelsea like they did against Inter Milan.
I don't know what you expect from Chelsea but I must tell you that they have been impressive and I can say that they are an underrated title contender. This was how they were underated and they went on to win the UEFA champions league against Manchester city.
Chelsea may have not meet the on paper top team but the team's they have put away are ones that are tough and could easily upset any team. I will be even more impressed if they can defeat Fluminense today.
