You were unlucky not to choose Chelsea while I myself was unlucky in the PSG vs Real Madrid match because I chose to bet on BTTS but in reality Real Madrid could not score a single goal... this is a shame. 
It's not a shame when you play against someone better than you. RM is not good enough, and I think it will be like that for the whole season. The last couple of seasons have not been particularly convincing. Several spectacular comebacks lulled them into believing that they are strong, but that is not the case. We just have to wait for the season to start to see how Real Madrid will perform throughout the season against Barcelona.
