Real Madrid and Barcelona are two traditional giants in La Liga, and many top players have played in these two football clubs, which has made both football clubs achieve excellent results in the Champions League in the past decade. However, Real Madrid's achievements in the Champions League are more convincing than Barcelona's, because three consecutive championships are the goal that many teams can't achieve. However, Real Madrid has achieved such results in the Champions League.
There are also many grievances between Real Madrid and Barcelona, which makes the two clubs rarely deal directly with players. Once the players of the two clubs transfer, the words of the other side are likely to cause friction and contradiction between the fans of both sides, which is enough to show that the two football clubs are actually very important competitors in the domestic league. However, in the domestic league, Real Madrid's performance is not as good as that of Barcelona, because Barcelona won the domestic league championship many times after 2 1 century, which also makes Real Madrid's league championship after 2 1 century far less outstanding than Barcelona.
Although the two teams have achieved excellent results in the past ten years, now the two football clubs are also in trouble of upgrading. If the two football clubs do not upgrade their players quickly, it is likely to lead to a serious decline in the strength of the team, thus affecting the competition between the two football clubs for the league title and the Champions League title.
