Spurs won 3-0 on Tuesday night, though Vicario felt they could've been more composed in the second-half.
He explained at the final whistle: "We proved what we can do two days before this game. We did well for 60 minutes but we need a bit more composure across 90 minutes. I had this feeling that if we were a bit more calm this result could’ve been better and goal difference is important in this league phase. But we're still aiming for top eight.
"They had some shots outside the box, they are aggressive, man to man all over the pitch. If you miss a pass or don't win a second ball we are a bit open. Their game is to open up teams. Three good points and we'll see. Two more games to play in the league phase, next round will be tough against Dortmund."
Asked if momentum is now with Spurs, Vicario added: "Probably, I hope so. We are judged every three days and football can change every three days in a good or bad way. We have to keep momentum, you need to have balance when things are going well or bad. If the result is good everyone is happy but we need to stay calm and focused and try to do our best."
