Indeed, Benfica coach Jorge Jesus now feels that the fact they are facing a side of the calibre of Spurs means the competition is more reminiscent of the UEFA Champions League.
"Tottenham are a top-class Premier League team, it will be hard but they have to respect Benfica too, they will be facing an excellent team," said Jesus after they eased past PAOK.
"Now it's like the Champions League."
Benfica midfielder Nicolas Gaitan added: "We have time to analyse Tottenham, but it's always good to face great teams, let's see if we are good enough."
And Salvio added: "The matches against Tottenham will be two finals, we have to play our best football as otherwise it will be hard to advance."
