The Swedish hitman admits he is having fun re-writing the record books after picking up his third winner's medal in just four months since his big-money move from Inter Milan this summer.
"It's fantastic. It's enjoyable to make history, although I've only been at Barcelona for a little time," he said.
"Barca have won everything, I hope we continue like that and we continue playing how we have been playing.
"One of the reasons why I came to Barca was to win titles."
