909 days! Barcelona’s current lineup for the last Camp Nou match was 12 players, with 7 players starting, including De Jong and Lewandowski.

Barcelona's official website lists where the current Barça players were when Barça played their last game at Camp Nou.
909 days, this is the time it took from the last time Barcelona played at the Nou Camp to their return to the home court again this Saturday. On May 28, 2023, Barcelona defeated Mallorca 3-0 to complete the 37th round of La Liga and finally won the championship. Now is a good time to look back at what the players on the current roster were doing back then.
The first is the players who were at Camp Nou at that time. As many as 12 players who now play for Barcelona took part in that match. Seven of them started: Ter Stegen, Balde, Christensen, Kounde, Garvey (who scored the last goal), De Jong and Lewandowski. Eric Garcia, Ferran and Rafinha started the game from the bench. Pedri and Araujo missed the game due to injuries.
The remaining players are either not in the first team lineup or playing for other clubs. For example, there are four current Barcelona players: Kubasi, Yamal, Bernal and Marc Casado.
The day before Barcelona faced Mallorca, Kubasi and Yamal were participating in the quarter-finals of the European U-17 Championship in Budapest. As the starting players of the Spanish national team, the two helped the team defeat Ireland 3-0. Kubasi from Rocca Fonda scored the goal that sealed the victory. As for Casado, the player from San Pere de Villamayor represented Barcelona B against Logroñes on May 27, winning (1-0) in the last Federal First Division match at the Johan Cruyff Stadium and advancing to the play-offs. On the same day, Bernal participated in the Catalunya Cup quarter-finals and played for the Barcelona Junior A team. Although he started, he eventually lost to Girona in a penalty shootout.
Finally, there were seven players who had not yet joined Barcelona or were on loan. Fermín Lopez happened to be on loan to Linares and played 85 minutes against San Fernando on May 27 and provided one assist. The remaining players have no connection with Barcelona. Gerard Martin plays for Cornelia and started against Numancia on 27 May. Juan Garcia came on as a substitute in Valencia's match against Espanyol, a game that ultimately led to Espanyol's relegation. Szczesny played the entire game for Juventus against AC Milan, but the Bianconeri lost. Dani Olmo was playing for Leipzig at the time and provided an assist against Schalke 04 on May 27. At the same time, Rashford wore a Manchester United jersey and helped the "Red Devils" win 2-1 against Fulham on May 28. Ronny Baddji played in Copenhagen's match against Viborg.
