David Moyes feels it is too early to say whether Everton's stunning win over Chelsea will prove the season's turning point or a false dawn.
The Toffees breathed new life into their disappointing campaign with a dramatic penalty shootout win at Stamford Bridge in an FA Cup fourth-round replay 10 days ago.
After spending most of the season in the bottom half of the Barclays Premier League, the Merseysiders are hoping to build on the emotional victory to finish strongly in both competitions.
They followed up the Chelsea result with a 2-0 win over Sunderland on Saturday to move into mid-table, but their work would be undone if Reading spring a surprise in the FA Cup fifth round tonight.
Moyes said: "I don't think we have had our feet off the ground for a long time.
"We have done nothing this year to jump up and down about and say we are doing well.
"We had a really good victory against Chelsea, but that's all.
"Two weeks ago you were probably asking, 'Were we in a relegation battle?' and I would have said 'yes'.
"We could well still be if we don't keep picking up points.
"We have got to do that first and foremost and if we do pick up the points, then we will try to see how close we can get to the European places."
Moyes has made no secret of his desire to win the FA Cup and bring silverware to Goodison Park for the first time since 1995.
The Scot will celebrate nine years in charge this month and feels success is long overdue.
He fielded a strong side in the third round at Scunthorpe and even though the Chelsea win showed his side at their determined best, he is taking nothing for granted at home to npower Championship side Reading.
Moyes said: "It has given us a feeling that if we can put out the holders we can beat anybody but we understand how hard this game is.
"Reading came to Merseyside last year and put Liverpool out. We are not going to be taking them lightly.
"I have to keep reminding myself and the players we have had some bad days in the FA Cup in the past. Let's make sure this isn't another one.
"We will give Reading the respect they deserve. They are a good team with some very good players."
Everton striker Louis Saha is in contention after escaping from a car crash unharmed on Sunday night, although he did have a hamstring problem on Saturday.
Midfielder Marouane Fellaini is the biggest injury doubt with an ankle injury.
