AZ Alkmaar have a one-goal lead to defend in their Europa League quarter-final against Valencia after winning the first leg 2-1 at the ASAF Stadion.
Dutch league leaders AZ went ahead via Brett Holman’s goal right at the end of a first half in which Valencia had looked very comfortable for the most part.
The Spanish side then drew level six minutes after the break via Mehmet Topal’s fine header, but Maarten Martens struck with 11 minutes remaining to hand the advantage to Gertjan Verbeek’s side.
