History and precedent crumbled Wednesday as free-scoring Bayern Munich travelled to Villarreal,

currently Spain's seventh-best side, and came up entirely empty-handed in a 1-0 

defeat that occasionally threatened to turn into two or three for the home side.

How'd the Yellow Submarine pull off such a stunning upset? We can turn to this

5 Reasons Bayern Munich Will Beat Villarreal In The UEFA Champions League" to dissect where the reasons went wrong.

Reason #1 — "Goals, goals, goals"
This one was a very valid point about how Bayern

entered the match averaging 3.75 goals per game in the UCL with Robert Lewandowski (12 goals)

and Leroy Sané (six) leading the charge. In fact, they'd only failed to score on one previous occasion this season

a DFB-Pokal defeat to Gladbach back in October. 
But Bayern only had one shot on target in the opening hour

at la Cerámica, and had it gone in, it would've been chalked off for offside.
