Chelsea versus Real Madrid fixture is definitely a 50-50 chance but I am going to lean towards the side of Chelsea mainly because they are seems to have inculcate the winning mentality in the team even at the face of adversity, they have been playing well and winning games as if the club is not under pressure from the government and football organizations. I doubt if Real Madrid team is as strong mentally as Chelsea.
Chelsea are a seasoned cup fighter but still no one can match Real Madrid in this respect, not even Liverpool which have had some of their brightest seasons. Chelsea are under pressure from the situation their former owner is in plus they are not the best team in England so I also rate Real Madrid as the pair's favourites.
