Barcelona fullback Daniel Alves says they're still getting used to the methods of new coach Tata Martino.
Barca thrashed Ajax 4-0 in their Champions League group opener.
He told Barca TV: "We are still in transition as we seek our best and it's evidently not easy.
"I think we're on the right track and, although we've made adjustments to the team, we're still winning.
"What we're doing is not so different, but we are introducing new things to counter certain teams that just come to defend and we're looking at ideas for creating more goalscoring chances."
