Jose Mourinho's assistant was quite satisfied with his side's performance in the 2-1 victory over their rivals, and felt they could have scored even more goals with a bit more luck
Goals from Gonzalo Higuain and Cristiano Ronaldo helped Madrid to a 2-0 lead before Lionel Messi pegged one back, but the Catalans were unable to add another, and saw los Blancos win the Supercup on the away-goals rule.
"The team went for it from the very beginning and the game went our way with the early opener, and then a little bit more with the sending off," Karanka stated at the post-match press conference.
"We created a lot of chances. I think our win was fair, especially after watching the first half. The result is a fair reflection of what happened on the pitch.
"If we had scored all the chances we had in the first half, it would have been an even fairer result. It was a game for a title and this was the result we needed after the loss from the first leg.
"The most important thing was that we turned things around."
