The 45-year-old coach praised the Liga giants for not relying on their star names to secure victory following the 3-0 win on Sunday
The Liga giants coasted to a 3-0 victory without the influence of a number of key players after coach Tito Vilanova named six changes to the side who faced Paris Saint-Germain earlier in the week.
And speaking to reporters after the game, the Camp Nou assistant was full of praise for the strength-in-depth shown to negotiate a "tough" fixture.
Roura said: "We did not think much about resting players because we wanted to win. If we had a midweek game that would been different.
"It is difficult to pinpoint someone today. It was a tough game and Thiago, Song, Tello and Bartra were all fantastic. I praise the whole team. I am very proud of this squad.
"I had said how important it was to win this match. The league is simple now but the priority."
