Barcelona's star striker, Lionel Messi, scored the only goal in their 1-0 win over Real Madrid on Saturday night, as they secured their place in the quarter-finals of the Champions League. The Argentine's goal was his 45th of the season and he also became the all-time leading scorer in the competition with 79 goals.

In other news, there have been some interesting developments at Barcelona's second team, FC Barca B. The club has confirmed that their top scorer this season, Barreiro, will be substituted in the upcoming match against Augsburg in the Europa League.

The substitution of Barreiro comes after he had scored twice in two matches for the first team, but it is unclear why the club has decided to make him a substitute. However, it could be seen as a sign of faith in the younger players within the squad who may have more potential than Barreiro.

It remains to be seen how this substitution will impact the team's performance in the Europa League, but it certainly shows that the club is not afraid to take risks and give young talent a chance to shine. It is clear that the future looks bright for FC Barca B, and fans can look forward to seeing what the youngsters can achieve in the coming seasons.
