2009–10 UEFA Europa League knockout stage
The knockout phase of the 2009–10 UEFA Europa League began on 18 February, and concluded with the final at the Volksparkstadion in Hamburg, Germany on 12 May 2010. The knockout phase involved the 24 teams that finished in the top two in each group in the group stage and the eight teams that finished in third place in the UEFA Champions League group stage.
Each tie in the knockout phase, apart from the final, was played over two legs, with each team playing one leg at home. The team that had the higher aggregate score over the two legs progressed to the next round. In the event that aggregate scores finished level, the team that scored more goals away from home over the two legs progressed. If away goals were also equal, 30 minutes of extra time were played. If goals were scored during extra time and the aggregate score was still level, the visiting team qualified by virtue of more away goals scored. If no goals were scored during extra time, there would be a penalty shootout after extra time.
In the final, the tie was played over just one leg at a neutral venue. If scores were level at the end of normal time in the final, extra time would be played, followed by penalties if scores remained tied.
The draw for the Round of 32 took place on 18 December 2009, and featured the top two teams from each group in the group stage and the eight third-place finishers from the UEFA Champions League group stage.
The first legs of the first knockout round were played on 18 February 2010, while the second legs were played on 25 February.
