#1 Hit: Robert Lewandowski
Lewandowski was the X factor that Chelsea so desperately need to jump from Europa League winners to bonafide Champions League contenders. So, while Bayern's star man was causing problems early on, you could hear the confusion in the commentators' voice. Why was Olivier Giroud ball-watching so often and how exactly could he affect the game properly?
To his credit, there were brief flashes of what you'd expect from a top-class striker. Instinctive link-up play, doing well to fashion half-chances with your back to goal is easier said than done - not least against Bayern's three-man backline.
But ultimately, he and substitute Tammy Abraham were nullified by a side who did their due diligence and were prepared: balls into the box were either cleared altogether, or those same players weren't in the best positions to receive probing passes near Manuel Neuer's goal.
Even a hint of indecisiveness was pounced upon by Bayern defenders, as evidenced by Abraham's ineffective cameo - this was a different level entirely to the rigours of top-flight football. Lewandowski, meanwhile, would have been frustrated not to have earned a first-half brace but was facing a motivated goalkeeper in Willy Caballero, making his first UCL appearance since March 2017.
Crucially, he kept his head up and turned creator with two clever defence-splitting passes early in the second half. The combination play between him and Gnabry was beautiful as it was simplistic and spun Chelsea out of shape on the counter.
Then as you'd expect, he turned scorer to apply the definitive touch on Davies' brilliant solo run - sending Bayern home with a comfortable 3-0 first-leg lead; precisely the type of display we've come to expect from the world's best striker.
