Based on what we see, Liverpool's performance in the last 5 matches has been quite consistent in winning and Real Madrid has lost 2 times in the last 5 matches. In the Champions League, Real Madrid's performance is also a little different this season, unlike previous seasons which were able to achieve a convincing victory in the first round of the UCL, but if you look at the statistics of their meetings so far in the UCL, Madrid has always won matches against Liverpool, let's see if there will be a surprise in their meeting this time.
As a Real Madrid fan, I'm more nervous about the upcoming UEFA Champions Liverpool game against Liverpool than I was when Barcelona visited Santiago Bernabeu for the first El Classico of the season and the reason is because Liverpool have been immensely impressive in the European Cup this season. They're the only club that's won all their games in the competition this season and playing against them at Anfield will definitely be a difficult one for Real Madrid. That being said, I'm optimistic that Real Madrid stands a very good chance of either winning the game or getting a point at the end.
You don't have to be nervous as a Madrid fan, Madrid have had more challenging situations worse than this especially those days of home and away games yet they pulled through. Given the pedigree and the calibre of players in Madrid, I'm not even moved by statistics been presented as Liverpool stance at the moment. That El classico game was a one off mistake that I believe won't repeat itself, at least we know the caliber of players currently in Barcelona and what they can do so I believe next time they will prepare better. Since you're optimistic about Real Madrid stands concerning the game, then you shouldn't be nervous as Madrid will do what they know how to do best.
