The knockout phase of the 2012–13 UEFA Europa League began on 14 February with the round of 32 and concluded on 15 May 2013 with the final at Amsterdam Arena in Amsterdam, Netherlands.
All draws are held at UEFA headquarters in Nyon, Switzerland.
[1] Matches may also be played on Tuesdays or Wednesdays instead of the regular Thursdays due to scheduling conflicts.
The team that has the higher aggregate score over the two legs progresses to the next round.
In the event that aggregate scores finish level, the away goals rule is applied, i.e. the team that scored more goals away from home over the two legs progresses.
If away goals are also equal, then thirty minutes of extra time are played, divided into two fifteen-minutes halves.
The away goals rule is again applied after extra time, i.e. if there are goals scored during extra time and the aggregate score is still level, the visiting team qualifies by virtue of more away goals scored.
If no goals are scored during extra time, the tie is decided by penalty shootout.
If scores are level at the end of normal time in the final, extra time is played, followed by penalties if scores remain tied.
3–3 on aggregate; Zenit Saint Petersburg won on away goals.
