Valencia were roundly booed for failing to win against local rivals Levante on Sunday in La Liga and Unai Emery badly needs a win against AZ Alkmaar on Thursday night in order to placate fans who have witnessed their side fail to win at home in the past six weeks.
They will also hope to join Atletico Madrid and Athletic Bilbao in the semi-finals as the two Spanish sides are in a commanding position following their wins over Hannover and Schalke 04 respectively in the first leg. The Germans will not give up easily, however, and have vowed to do their utmost to reach the last four and prevent the dominance of Spanish clubs in Europe this season.
The final match sees Sporting Lisbon visit Metalist Kharkiv with the Ukrainian side needing just one goal in order to lead the tie on away goals after they scored a last-gasp penalty in Lisbon in the reverse fixture.
