Darwin Nunez scored the winner as Benfica beat Ajax in Amsterdam to reach the Champions League quarter-finals.
After an entertaining first leg ended 2-2 in Lisbon, the return was far tighter and the visitors had done little to threaten before Nunez struck.
Ajax dominated and Sebastien Haller had the ball in the net early on, but Dusan Tadic was offside in the build-up.
Yet for all the home side’s possession they struggled to break down a resolute Benfica defence that was well marshalled by veteran centre-backs Nicolas Otamendi and former Ajax and Spurs man Jan Vertonghen.
In the end it was Benfica’s vociferous travelling support who were left chanting as their players enjoyed celebrations on the pitch, with the Portuguese outfit reaching the last eight of the Champions League for the first time since the 2015-16 campaign.
