Barcelona assistant coach Jordi Roura has refused to blame the officials for his side's 4-0 defeat to Bayern Munich in the Champions League semi-final on Tuesday, despite insisting two of the goals shouldn't have stood.
Arjen Robben's 73rd minute goal gave Bayern a convincing 3-0 lead, but Barca appealed the decision after Jordi Alba appeared to be impeded by Thomas Muller in the build-up.
But Roura denies the decision impacted Barcelona's hopes of progression, admitting the Spanish side were inferior to the Bundesliga champions.
"In the first half we competed well but they scored from a set piece and we knew coming into the match that they were a physical side; strong and powerful," he said. "In the first half we had our options. What hurt us the most was the second goal. We tried to carry on but Bayern made it very difficult.
"There were a couple of goals that were clearly illegal. We haven't been lucky throughout the competition this year and we weren't fortunate with the decisions tonight but I won't say that the referee had an influenced on the final result."
Roura has conceded Barcelona will need a miracle to keep their Champions League season alive, but insists they will fight for a positive result at the Camp Nou.
"The players are sad and frustrated," Roura said. "This was a game that we were excited about and the result is awful. We're all sad but this is football. We have to keep on going.
"The defeat is very painful and it complicates our chances of getting to the final. We will try to turn this tie around in the return leg. Miracles are hard to get and the 4-0 result is complicated, but our obligation is to fight as hard as we can. We will keep on trying until the referee blows the final whistle."
Lionel Messi returned for Barca after three matches on the sidelines and Roura has praised the Argentinean for his impact while under an injury cloud.
"Leo put in an incredible effort to be here," Roura added. "He managed to play the 90 minutes and he did what he could. I'm proud of how hard he worked to be here."
