Watch the first half highlights wherein Bayern Munich trash the Olimpiakos defense

At home Bayern Munich are next to unstoppable. Bayern knows that. Olympiakos knows that. The only question is can Olympiakos hang on to grind out a defensive draw, and perhaps snag a goal on the counterattack?

Well if the first half is any indication, the answer to that question is "No" because Bayern Munich absolutely eviscerated the Greek side in the first 20 minutes, hanging three goals on them from Bayern Munich's potent attacking force.

Douglas Costa got the party started, pouncing on a rebound following a thunderous shot from Jerome Boateng inside the first 10 minutes.

Good news for Arsenal as Bayern take a 1-0 lead on Olympiakos through Douglas Costa. #UCLonFOX https://t.co/QvukCIhstY

Minutes later it was Robert Lewandowski, who it turns out is completely lethal when you leave him unmarked.

Bayern Munich strike again as Lewandowski makes it 2-0 with barely 15 minutes played. #UCLonFOX https://t.co/cvBiZ1SyUS

Rounding it off was Thomas Müller who got the easy tap-in that deserves to be added to training reels the world over on how to read opposition positional breakdowns.

Bayern can't stop scoring as Muller makes it 3-0! Arsenal have one less game to worry about, it seems. #UCLonFOX https://t.co/DGb0rTa3Mh

Just another half of Bayern Munich out there being Bayern Munich.
