Real Madrid and Barcelona have been two of the most successful teams in Spanish football for many years, with both clubs winning numerous titles over the years. However, when it comes to their performance in Europe, Real Madrid has consistently outperformed Barcelona in recent years.

In the La Liga team's group stages, Real Madrid has won four of its last five appearances, while Barcelona has only won once. This is partly due to the fact that Real Madrid has had a more dominant squad than Barcelona in recent seasons. The club has also had more success in the Champions League, having won three of its last four appearances.

One of the key factors behind Real Madrid's success in Europe is its ability to dominate possession on the pitch. The club has a strong midfield and a high-pressing system, which allows them to control the game and create chances for their forwards. Additionally, Real Madrid has a strong defensive unit, which helps to prevent their opponents from scoring.

On the other hand, Barcelona has struggled in Europe in recent years. The club has struggled to find its form in the Champions League, failing to win any of its last six appearances. This is partly due to the departure of some of the club's key players, such as Lionel Messi and Luis Suarez, who have moved to other clubs.

Despite this, Barcelona still has a talented squad and has shown flashes of brilliance in the past. The club's fans remain passionate about the team and continue to support it throughout its ups and downs.

Overall, Real Madrid and Barcelona have both been successful teams in Spain and Europe, but Real Madrid has consistently outperformed Barcelona in recent years. The club's dominance in possession, strong defense, and talent-laden squad make it a force to be reckoned with in the Champions League.
