The Scottish side take on the Catalan giants in their final Champions League group stage match on Wednesday night and Finnish striker Pukki feels the pressure is off which could prompt a spirited showing.
"We can win it and we all want to win it," he told the club's official website. "We want to show in this match that we can win games in the Champions League.
"As much as we wanted to still be in the tournament at this stage we have nothing to lose now. We can go into the game with no pressure, and the Camp Nou is one of the best places to play."
Speaking of places he enjoys playing, Pukki says there is no better place than the Hoops' own backyard to experience a brilliant football atmosphere.
"This is one of the best places to be if you want to play in the Champions League," he added.
"I had heard things about Celtic Park on European nights, I had heard it was amazing and it was all true. All of my friends and family who came over really loved it as well.
"There was always someone here. My Dad came over for the first game and I had friends at the last two, they really enjoyed it. The experience really did live up to expectations."
