I disagree agree with you on this, Chelsea will be motivated to play with anger after Finding it difficult to get to the top4 in the EPL and with the Champions League as their only hope to play in the Champions League they will shock Real Madrid and looking at their past history you can see that Chelsea have a good record against Real Madrid except last season that Real Madrid humiliated them in the knock out stage.
Chelsea will be eyeing to get a win in the first leg clash against Real Madrid regardless of their poor performance when it comes to Champions League Chelsea can not lose easily to any team not even to Real Madrid whom they know has more chances of beating them if they don't play very well .
I can't deny the optimism of Real Madrid supporters about his chances in the Champions League this season. Chelsea is undervalued and perhaps underestimated because of the team's mentality and recent form, but I don't agree with that opinion either.
If Chelsea is really a weak team, they shouldn't have made it to the quarter-finals. I know that Madrid are the favourites, but not all the favorites can win all the games and win the title. I'm not going to compare the achievements of each team, but their performances on the pitch are valid evidence even if everyone has assumptions and tries to argue in other ways.
