Borussia Dortmund forward Robert Lewandowski believes attack is the best form of defence ahead of Tuesday's Champions League clash with Shakhtar Donetsk.
The German giants find themselves in pole position to progress to the quarter-finals after earning two valuable away goals in their 2-2 draw in the first leg.
However, having witnessed the threat posed by Shakhtar in Ukraine, the Poland international believes Dortmund can ill afford to rest on their laurels against a "dangerous" side.
"Donetsk scored twice against us in the first leg and they showed how dangerous they are. We can’t play for a draw, or aim to get a 0-0 or 1-1. That would be far too dangerous," he told Bundesliga.com
"We desperately want to win it, even if it’s not going to be easy. We know that we can score against Donetsk because we showed that in the first leg, and we should also get at least one goal on Tuesday.
"We’re at home after all, so we’ve got to be positive. We want to, and have to, get into the next round and that is the clear objective on Tuesday."
Meanwhile, the 24-year-old also played down the significance of Shakhtar's away form.
"They are always good away from home. They’ve now played their first game after the long winter break in the Ukrainian league so they’ll be fit and certainly in more of a rhythm than they were in the first leg," he added.
"But that’s not going to be decisive. We’ve got to ensure we focus on ourselves and play the best we can. That’s what matters the most, and that way we’ll be successful again."
