While the Europa League will continue to offer respite from an otherwise difficult season for Forest, the additional games present challenges.
Forest will take on Porto in the quarter-final on 9 and 16 April, welcome Aston Villa to the City Ground in between the two legs and then host Burnley the following weekend.
Winning games means positive momentum and that can only be a help when it comes to fighting to stay in the league.
But it also means more games and Pereira, who is set to take charge in his first European quarter-final, must find the balance between keeping his side in the top flight and managing the demands of competing in Europe.
“When we win it’s different,” Pereira said.
“The spirit is different, the energy is different and the boys deserve it because they are a fantastic group, very good players and with team spirit, character – we showed everything today.
“I don’t have any doubt that we have the quality and we will compete to achieve our targets.”
Yates added: “That winning feeling is special, you want to keep that momentum going.
“Momentum at this stage of the season is huge. We’re not going to get ahead of ourselves. Recover now, focus on Tottenham now and keep building, keep getting those wins.
“It’s not over yet, we’re still dreaming.”
