Barcelona coach Luis Enrique feared his side would slip up in La Liga on Saturday, during their 8-0 rout of Cordoba.
It took until the 42nd minute for the league leaders to break through, with Ivan Rakitic putting them ahead - but the former Real Madrid and Barcelona midfielder feared the goal would never come.
"It's true that we are in really good form, but with each new game you have to create the type of chances that help you get those good results," Luis Enrique said.
"Today the result was a big one thanks to the efficiency we had.
"But up to the 39th minute, we had two or three clear chances and it looked like the ball didn't want to cross the line.
"We were all worried about this being one of those uninspired matches. But it wasn't like that.
"The goals from Ivan and Luis [Suarez] helped us to a 2-0 lead at half-time and in the second half the team performed at a high level, creating chances and being very effective.
"I'm happy because we grabbed three key points."
"To arrive in the semi-finals of Champions League with the season we are having reinforces our strength a lot, but we have to back this up in a really difficult knockout tie," he said.
