The Latics paid for failing to find the net despite dominating for large spells, as Matt Jarvis and Kevin Nolan scored either side of half-time.After three consecutive away games in the league, Wigan now have five games to maintain their eight-year stay in the top flight - starting with a home fixture next Saturday against Tottenham Shaun Maloney was at the heart of Wigan's best attacks but the Scot was denied by Jussi Jaaskelainen in the first half, and the West Ham goalkeeper also saved James McArthur's shot following Maloney's clever cut-back.The results at this stage of the season, you can't rely on other people. We've got 31 points that's nowhere near enough what we need and we are focusing on ourselves," he said.Martinez said: "In the league we need to find a way to get the points that we deserve. If we play the same level as we have in the last two games in the next five, the points will come.It's a very good run of games that we have got in the next five; we have three at home and we have enough opportunities to carry on playing in the manner that we did and being able to get the rewards.He added: "We should have had something from the game. The second-half performance was as one-sided game as you will see away from home and to lose [the half] 1-0 was difficult to explain. But you get through those periods and the two teams looked a little bit - not tired - but affected by the fixtures on Wednesday.
