I don't agree with saying that before Messi came Real Madrid dominated the league. Yes, it may be true that from year to year Real Madrid has always been a candidate in the list of champions, but it is not that easy for them to take it. Even the nickname El Clasico was born long before we knew Messina, it shows that Barcelona has always been a scary team.
The nickname El Clasico is because of the meeting between Barcelona and Real Madrid and it has nothing to do with any player or anyone in the two teams so it is still mentioned today when there is a match for both of them in any league. So what Barcelona is doing at the moment is just trying to improve his form so that he can be on a strong path like it has seen in the past.
Yes El Clasico is a battle of two teams that has been going on for a very long time. But I want to talk a little bit about the players in it. We know that Real Madrid and Barcelona have been strengthened by two players who have become football icons in the last decade. Namely Messi in the stronghold of Barcelona and Ronaldo in the stronghold of Real Madrid. It becomes interesting because many are comparing the quality of these players. Messi is better than Ronaldo and vice versa, if these two meet we are not only interested in El Clasico but also in these two players.
