Goalscorer Gary Hooper is confident Celtic can score in Finland and progress to the Champions League play-offs after coming from behind to beat HJK Helsinki at Parkhead.
Rasmus Schuller had stunned the home crowd by netting a potentially crucial away goal early in the second half.
But Hooper equalised before Charlie Mulgrew headed home the winner on the night and the Englishman is optimistic the Bhoys will score in Finland and progress.
"I thought we played well," said Hooper.
"We didn't take our chances in the first half and conceded a sloppy goal but we came back and scored two good goals. We did really well to respond.
"We had to step it up a level and we did. I thought we played really well."
HJK are midway through their season, while Celtic only begin their league campaign against Aberdeen on Saturday.
And the 24-year-old striker believes the sharpness that the team pick up from that game could swing things in Celtic's favour when they travel to Helsinki.
"We passed the ball well, the fitness levels were up there," he added. "The sharpness is not there yet but we are getting there.
"We have got an SPL game with Aberdeen and take the sharpness out of that into Wednesday.
"We have just got to play like we did. We will not sit in and defend. We will go there and play football.
"We have enough attacking players to score goals. We are good on the counter-attack.
"I look to score in every game and if the chances come like they did in the first leg then I think we have a good chance."
