Ruud van Nistelrooy gave Hamburg a 2-1 win over Standard Liege in their Europa League quarter-final first leg in Germany, while Valencia were held to a 2-2 draw by Spanish rivals Atletico Madrid.
Belgian visitors Standard took the lead after 31 minutes through Dieumerci Mbokani.
Mladen Petric equalised with a 42nd-minute spot-kick and Dutch striker Van Nistelrooy, who signed from Real Madrid in January, completed the turnaround just before half-time.
The winner after next Thursday’s second leg in Liege will face Fulham or Wolfsburg.
A second-half blitz saw Valencia come from behind twice at the Mestalla.
The winning side in next week's return faces Benfica or Liverpool in the semi-finals.
