Fulham's Brian McBride says there is no room for complacency on the final day of the season.
Victory for Fulham at Portsmouth will see them retain their Barclays Premier League status and complete one of the greatest escapes in the history of the top flight.
Fulham looked doomed last week when they trailed 2-0 to Manchester City but a stunning fightback secured a 3-2 win and a solid 2-0 success over relegation rivals Birmingham City on Saturday has left the Cottagers in a great position to beat the drop.
"It has been a great turnaround," said McBride. "It was always going to be emotional on Saturday as it was a very important game for both teams.
"We've worked so hard to make sure we maintain the right focus and right attitude going into our games.
extremely vocal
"The manager has kept us focused and we went about our business in the same way. We focus on the game itself and not worry about the position because going into a game you can't be worrying about where you're at.
"As you can expect the atmosphere in the dressing room was very good after the game but we're not under any illusions that this is over. We still have a job to do and it's going to be a tough one.
"Our confidence has grown for sure and you can see that with our composure. It's going to be a very difficult game on Sunday and I don't think any team in this league looks past the next game. They (Portsmouth) have great support there and they'll want to do well.
"Our fans were incredible on Saturday and they have been since we've been in this position. They've been extremely vocal and extremely supportive and it makes a big difference.
"Last weekend when we were 2-0 down against Manchester City we came out at half-time and they were still belting away - that can only do good things to you as a player.
"You play this game for the enjoyment and for the passion and you can see that in our players and supporters. The support has been great and our fans will play a huge part on Sunday and one we are grateful for."
