Manchester United boss David Moyes hopes his side's Champions League win over Olympiakos can be a turning point in their disappointing season.
Robin van Persie's hat-trick overturned a 2-0 deficit from the first leg to send United into the quarter-finals.
"I don't want to come out and say: 'This is the moment'," said Moyes. "But I hope it is."
Defender Patrice Evra added: "Everyone thought we were out, but we showed Manchester United are still alive."
Moyes, who has been under growing pressure following Sunday's 3-0 home defeat by Liverpool, said he still needed time to make his mark on the club.
"This is a work in progress and it will take time to get it as we really want it," said the Scot, whose team lie seventh in the Premier League table.
"It is a big job. I have got a lot of things I want to do, but the players gave the crowd something after we lost to Liverpool and we are delighted to see Manchester United in the last eight of the Champions League."
Moyes also insisted he was not feeling any pressure from inside the club, claiming it was all coming from the media.
"There are stories of this player falling out, or that one falling out, but it is rubbish," he said.
"People are looking for reasons why we are not doing well and it is only because we have not been playing well."
Although Van Persie scored the goals before going off on a stretcher with a knee injury, Moyes praised the contribution of recalled 40-year-old Ryan Giggs, who had a hand in the first two goals.
"Ryan's passing was fantastic," said Moyes. "His overall play was really good and he defies his age.
"He has not played much recently, but I felt, tactically, I needed him to play a certain role. He carried it out perfectly."
Moyes does not think Van Persie's injury is serious and was delighted with the striker's contribution.
"To score a hat-trick in the Champions League is a big thing," he said. "There are only certain players in the world who are capable of it and Robin van Persie is one of them."
