The Dutch referee has received his fair share of criticism for his decision to award the Catalans a second penalty after Alessandro Nesta's infringement on Sergio Busquets five minutes before half-time.
However, Kuipers declared that he was pleased with his display and does not feel guilty about any of his decisions.

Uefa does not allow its match officials to comment on specific situations, but Kuipers hinted that he has no regrets about his controversial calls.
"The fact that we have a good feeling about the match says it all. My phone has been ringing non-stop, and it's nothing but compliments," he added.
Barcelona qualified for the semi-finals of the Champions League following Tuesday's victory after drawing 0-0 in the first leg at San Siro.
