I actually think the opposite, Barcelona have failed miserably on the UCL stage after being defeated by Inter Milan in the first leg in a draw in the second leg which was played earlier this morning and that made their chance to qualify for the round of 16 almost of course The mentality of the Barcelona players is not good.
and that is in contrast to the Real Madrid team which is very stable at the moment.
El CLasico is always interesting and of course played with high tension and if you look at the consistency of the two teams at this time I believe Real Madrid will be able to win over Barcelona and I will bet big on their victory in this match.
In the champions league Barcelona really did not show a good performance. even inter able to hold Barcelona draw. even though Inter are actually not in good shape in Serie A. but in the Champions League Inter are playing well. and conversely Barcelona had a good performance in La Liga but in the Champions League it looks like Barcelona is really disappointing. Even though I see Barcelona's performance can be more than that with the quality of the players who are very good.
for El classico I still can't see which team is superior. But Real Madrid are far more consistent in La Liga and in the Champions League. But even Barcelona in La Liga is quite consistent. so I still see a 50:50 chance. between the two. and haven't decided where to bet yet.
