The Portuguese legend feels the club’s supporters can play a huge part in spurring the team on the Europa League showcase event in Amsterdam later in May
The Turkish side lead 1-0 from the first leg last week and Nene, who made over 600 appearances for the Portuguese club, thinks a vibrant atmosphere at Estadio da Luz is the key to helping them overturn the deficit.
"I expect to see a stadium full to 65,000 people, helping our team on," he told the club’s official television channel.
"Let's show the Fenerbahce we are able to be beat them and with the help of the crowd I feel we can win and get to the end of the competition."
The visitors are without suspended duo Pierre Webo and Mehmet Topal, while Jorge Jesus’ side will be missing Rui Fonte, who is out with a knee injury.
