The Catalan club fielded the youngest side in La Liga this season as they were held to a 0-0 draw with basement club Huesca.
Ernesto Valverde was pleased with the way his back-up Barcelona side performed against Huesca despite being held to a 0-0 draw on Saturday.
The LaLiga champions made 10 changes to the team that started in their Champions League quarter-final first-leg win against Manchester United at Old Trafford and the bottom side used that to their advantage but could only secure a goalless draw.
With United visiting the Camp Nou on Tuesday, Barca will have their rested stars back. However, Valverde hailed the display of his makeshift line-up following the match at Estadio El Alcoraz.
"We're happy because it was a difficult match for us. A lot of new people came in, but they understood what they had to do," he said.
"I did not want to play [Nelson] Semedo or [Jordi] Alba because they played the full game the other day. Sergi Roberto had muscle discomfort, too. We were forced to play with Malcom on one wing and Wague on the other.
"It cost us a little at the beginning, but we're happy because the players went above and beyond, and we had our options. It was tough, but I thought that's what we needed to do.
"You have to understand the circumstances around the game. They were not normal debuts, like when a player debuts alongside the first-choice players.
"We changed a lot of players, the way to play and against a team that's playing against relegation."
Barcelona are 12 points clear at the top of the LaLiga table and will now channel their focus to the Champions League tie against Ole Gunnar Solskjaer‘s Red Devils on Tuesday night.
