Matthew Upson remains confident that West Ham United will stay up with three games left in the Barclays Premier League season.
The Hammers are three points ahead of the relegation zone, despite their 3-0 defeat at Liverpool on Monday, although 18th-placed Hull City have a game in-hand at home to Aston Villa to play on Wednesday evening.
Regardless of what their rivals do, captain Upson believes the Hammers will pick up enough points from their remaining three matches to safeguard their top-flight status.
"It was a disappointing performance on Monday," said the England centre-back. "Liverpool played pretty well but we were quite disappointed after the last couple of games.
"I thought we didn't react quickly enough to situations defensively, which cost us really. Once you go behind at Anfield at the moment, they keep the ball so well and create space and move the ball so well and it's very difficult to get a grip of the game.
"I thought we had a couple of little decent chances in the second half when Franco came on and made a difference. He slid a couple of little balls through that looked decent, but we didn't particularly threaten and it made it a long evening for us.
"I don't think defeat has jolted the confidence because we know what's at stake on Saturday and I think it's going to be a survival match. Everything else goes out of the window at that point and the intensity we need to play with and how we're going to go about getting the points are all that matters. We'll have to be fully committed and do our jobs properly to get the points."
Saturday will see Wigan Athletic arrive at the Boleyn Ground fresh from their amazing comeback victory over Arsenal at the DW Stadium last Sunday.
The Latics recovered from two goals down in the final ten minutes to all but ensure their own Premier League status.
Roberto Martinez's side sit 15th in the table, seven points above Hull and four above West Ham, with three matches of their own still to play.
"We were travelling up on the coach, so we didn't see the Wigan match. It was a bit of a shock, but these things happen. I thought Wigan really did make a big surge for it and got their reward. They never gave up and produced a really resilient performance.
"I think that win has probably edged Wigan far enough out of it. Mathematically, that's not true, but realistically, looking at the form of Burnley, Hull and ourselves, it's highly unlikely that we're going to get enough points to catch Wigan."
While he may believe Saturday's opponents are safe, Upson also insisted that West Ham would emulate their achievement.
"I think we'll stay up. I've always said 'Yes' and I'll continue to say that. We'll definitely stay up. I'm confident."
