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.
Not only you, but I think what you feel right now is certainly felt by other Madrid fans, with the current condition of Madrid I think all fans will feel nervous, especially if they must to face a team that is fairly strong and in positive form at the moment, maybe if Liverpool and Madrid met last season then I am quite sure if you will feel confident to say that Madrid will win given their outstanding performance usually.
Madrid condition this season is very inconsistent and also limp both in the league and UCL so I think getting 1 point at Anfield later it is already a lucky for them, the atmosphere in UCL and La Liga is very different even though the El Classico match is considered very important, but the UCL match actually has a higher prestige holding the UCL trophy status as the highest trophy in Europe so far.
