Roberto Martinez insists it is still "achievable" for Everton to secure a top-four finish in the Premier League.
Martinez's men currently lie sixth in the table, eight points behind Liverpool who currently occupy the final Champions League berth.
However, the Toffees have a game in hand over their Merseyside rivals following the recent postponement over the Goodison Park fixture against Crystal Palace.
On Saturday, Martinez takes Everton to Stamford Bridge for a showdown with leaders Chelsea and he says his team know they must give their all to realise their ambitions.
Martinez said: "We're in a situation now where we're going to approach every game in the same manner: we want to win every game we go into.
"If we can get, at the end of the season, a points tally which is enough for a top-four position, we will welcome that.
"It's a specific league now. Clearly the margins are very small. The points difference to the top four now means it is still achievable for the teams in fifth, sixth and seventh, and we are going to give everything we've got."
The Toffees went down 1-0 away to Spurs in their last league outing, despite dominating for large spells.
"The disappointment we had at White Hart Lane when we lost to Tottenham is something we need to change, something we need to correct," Martinez added to the Daily Mirror.
"We need to use that experience to our advantage of when you are the better side and playing well, you need to win the football match."
Martinez is relishing the tough encounter away to Chelsea, who have never lost at the Bridge in the league under Jose Mourinho's stewardship.
"It's good to have aspirations, but it's important as well that we take it step by step," he added. "The game at the weekend will tell us a lot about that.
"I think it's important as a team that we keep working, keep developing, we keep getting stronger. But only when you get in a match-day experience against teams competing in the Champions League are you going to get a clear idea of how far we have come.
"We are facing a very good Chelsea side. As you know, it's one of the hardest places to go and get three points.
"It's going to be a terrific measurement for ourselves to see where we are."
