Valon Behrami admits West Ham's meeting with Bolton this weekend is a 'very, very important game'.
The Hammers have given themselves breathing space in the battle to beat the drop, opening up a three-point cushion on the drop zone.
They are, however, far from assured to be playing Premier League football next season and know there is still a lot of hard work to be done.
Back-to-back successes on home soil, over Birmingham and Hull City, have helped their cause considerably and results at Upton Park could go a long way to determining their fate.
Next up in the capital are fellow strugglers Bolton on Saturday, with both sides desperate to take something from a crunch contest.
A number of those on display will have been away with their respective countries in midweek, including Swiss midfielder Behrami, but the match is already weighing heavy on the mind of many of those set to be involved.
"This is a game like the Hull one (a 3-0 win), against a team on the same level and they are a physical team," Behrami told West Ham's official website.
"We need to win as we are at home and keep playing like we played against Birmingham (a 2-0 win) and Hull.
"This is a very, very important game."
