I also have the same fear on that match but funny enough some gamblers will tell you that those are the best matches to bet on than the ones with very small odds however from this 3.5 odds they gave real Madrid don't be surprised that gamblers who would go for that match will choose real Madrid over Liverpool even if they have a higher odd because changes can happen at anytime and who knows if real Madrid will come up because it only takes a moment to see another shape on a club, meanwhile for those who have a weak mind should avoid that match.
In this match I think Real Madrid will be victorious though they are the visiting team, playing Liverpool at Anfield and Liverpool being the only club who as yet to lost a march in the Champions League group stage this season. With this I think it's expected Liverpool to be having a lower odd here but if Real madrid wants to remain in the Champions League they seriously need this win, although it will be even more difficult since they have unfinished scores to settle in the Champions League with Liverpool, has often suffered defeat from them .
