Celtic go in search their first win of their Champions League group campaign on Tuesday night.
They're in Germany to take on Borussia Monchengladbach.
Brendan Rodgers' side were beaten 2-0 when the teams met in Glasgow, leaving them with just a single point from their opening three games.
But the Celtic manager is confident of their chances in Germany. "We were second best in the last game, there's no doubt about that," he said.
"It was probably one of the few games which in terms of performance level we fell below a standard that we set.
"For us this year's competition has been a brilliant experience for us and it will prove to be a great foundation for us over the next few years. The experiences of this tournament and playing against the great teams we've been playing against will help us for the future.
"For now the only thing we're concentrating on is giving it everything in the game. There is no doubt that we can win here. If we perform to the level that we know we can then it's a possibility for us - or else we wouldn't be here.
