Scott Brown says Celtic will be looking to get on the front foot and cause Barcelona problems in the UEFA Champions League.
The Catalan giants are due at Parkhead on Wednesday as Europe's premier club competition reaches Matchday Four.
Last time out, Celtic came agonisingly close to taking something from a trip to Camp Nou, but a first half lead was eventually overturned by Barca.
Neil Lennon's side spent much of their trip to Spain pegged back inside their own half, but Brown insists they will adopt a more positive approach when they return to home soil.
The Celtic skipper said: "We are going to have to go out and create a few more chances.
"We will hopefully attack a little bit more. It was hard at the Nou Camp, it is a huge pitch and they had a lot of possession. But it's hard when you play against teams who press you so high up the park.
"They do that to most teams in Spain and win three, four and five-nil week in, week out, so it shows we got our tactics spot on.
"But we are going to have to get more of the ball and try to keep it for longer periods.
"Losing in the last minute is always going to be hard, but that shows you how dangerous Barcelona can be. We have to stay focused the whole game."
Brown will lead Celtic out in midweek and hopes he has finally shaken off a niggling hip complaint that has been troubling him for some time.
The Scotland international added: "I am starting to feel a lot better. I have had a lot of rest and my body is slowly getting better and better.
"I have managed to play three games in a row and I am feeling the benefits.
"So hopefully I am over the worst of it. You can never tell what is around the corner but my body is feeling good just now and if I can keep training day in, day out, playing two or three games a well, I am happy with that."
