The 20-year-old scored twice on Saturday and admits it is a weight off his shoulders.
"It always helps your confidence to get off the mark," he told fcbarcelona.com. "It was a bit of a liberation for me and it gave me a real boost of confidence and calmed my nerves."
Next up for Barca is a Champions League clash at Panathinaikos, but while coach Pep Guardiola tried to keep his players' minds on the task in hand, the rest of Spain is already looking forward to next Monday's Clasico against Real Madrid.
"Wednesday is a key game for us. The Madrid game will come around soon enough," said Bojan.
"(Pana) are a hard team and they'll make it hard for us. We are playing for the top spot in the group."
