The 25-year-old midfielder felt the Blaugrana learned their lesson from last season's defeat to Neil Lennon's side and controlled proceedings from start to finish.Barcelona midfielder Sergio Busquets feels his side produced one of its most complete performances in recent times during Tuesday's 1-0 win away to Celtic in the Champions League.
The Blaugrana avenged last season's 2-1 defeat to Neil Lennon's men thanks to a late Cesc Fabregas' header, which sent the club top of Group H in the process.
"If it isn’t our most complete game, it’s one of them," the 25-year-old was quoted as saying by the club's official website. “We controlled the game well for most of the match. They only had one clear chance which was perfectly saved by Valdes and a couple of dangerous corners.
“Last year they beat us by playing this way and we knew that they would try to do the same thing. This time we moved the ball quickly, we played long balls when they were necessary and, in the second half, the goal gave us a bit of tranquility.”
Barcelona's victory came without Lionel Messi in the ranks, with the Argentina star ruled out of the clash with a thigh injury.
