Rui Costa is confident Benfica can beat Celtic for a second time when they travel to Parkhead on Tuesday.
The Portuguese side beat Celtic 1-0 at home last month to claim their first points in UEFA Champions League Group D.
But Costa believes Benfica must win again in Glasgow to boost their chances of qualifying for the knockout stages.
"Benfica are only thinking of victory," the midfielder told the Portuguese press.
"If we won in Lisbon it is possible to repeat that in Scotland.
"The team is ambitious. If we want to stay in the competition we cannot be interested in a draw."
Costa accepts that it will be a difficult, physical game against Celtic, but insists Benfica will relish the challenge.
"During the last few days the players have spoken a lot about the match against Celtic and the players are very prepared.
"We know the style of Celtic and it will be a hard match in a tremendous atmosphere.
"This is one of the most important matches of our season so far but we have no fear.
"The key is to be superior to Celtic at the physical side of the game."
