I have been waiting for this match for a long time. The previous El Classico was one-sided. Barcelona was a team that was completely upset then. Koeman turned the team into a wreck. But the scenario is different now. Xavi has been able to strengthen the Barcelona team again. Aubameyang and Torres have adapted well to the Barcelona squad. After all, the Barcelona team can now be considered strong. So, this match will be competitive.
In the coming El Classico, Real Madrid will still be a stronger team but the latest match between Real Madrid and Barcelona, after Xavi came, shows that Barcelona can have a good performance against Real Madrid. Real won that match but they did not won it too easily. Barcelona did make enough challenge to Real Madrid in that match and makes us feel like two teams now are at almost similar levels.
Barcelona will do want to win the El Classico, first because their proud of the club tradition, second because they need three points to secure their position in top 4. People are discussing about chance for Barcelona to make unbelievable come back and win La Liga. In my opinion, it is very over optimistic and impossible for them. Let's be realistic that Barcelona will fight for three points but not because La Liga trophy.
