Fenerbahce coach Aykut Kocaman has called the first leg of their Europa League semi-final against Benfica "the most important match in our history".
Kocaman's Turkish side are through to their first European semi-final after beating Lazio in the quarter-finals.
He said: "It is a milestone. We should aim to continue this success over the coming years.
"This is the first European semi-final in our history, whereas Benfica have been here many times before."
Benfica, who booked their place in the last four by knocking out Newcastle 4-2 on aggregate, will be without captain Luisao.
The Brazilian defender has a thigh strain and is likely to be replaced by Jardel, while midfielders Enzo Perez and Andre Almeida are also injured.
