Download Brighton & Hove Albion Vs West Ham United 1 - 1 (Premier League) Highlights Mp4
Declan Rice described the feeling as "horrible" after West Hams Premier League draw at Brighton effectively ended the Londoners Champions League hopes.
The result leaves the Hammers in sixth and needing to bridge a five-point gap to fourth-placed Chelsea, with two games remaining.
Liverpool also sit a point above David Moyes side and have the benefit of a game in hand.
"We cant be relying on other teams to lose," West Ham midfielder Rice told Sky Sports.
"We have to go out and win - weve drawn too many and lost a few. Its obviously horrible because we had the Champions League in our sights."
Had Said Benrahma not scored a superb late equaliser, the visitors evening on the south coast might have ended with a fourth defeat in five games, with Craig Dawson and Tomas Soucek both heading earlier opportunities wide.
And Moyes, who felt their top-four aspirations had already disappeared, is now hoping his side can rouse themselves to earn a place in the Europa League.
