Chelsea headed into the game with a lot of pressure on their shoulders.
The Blues did beat Leeds United 1-0 in the Premier League this past weekend but it was their first win for some time and a rare goal in a season that has seen them struggle to hit the target.
And as they were 1-0 down from the first leg in Germany, a Chelsea win on Tuesday did seem pretty unlikely.
However, the west Londoners dominated the first 45 and opened the scoring after 43 minutes via Raheem Sterling, though they probably should have had 2-3 goals by that point anyway.
Kai Havertz then stepped up and scored from 12 yards eight minutes into the second half to send Chelsea through to the quarter-finals.
Following the game, details of a spat between Reece James and Emre Can have been revealed.
James even cheekily squirted water in the direction of the German during the spat.
Who has kept the most clean sheets in a single Premier League season?
