Roberto Martinez says Wigan will not be relegated from the Premier League despite missing the chance to move off the bottom by drawing with West Brom.
The Latics wasted a number of chances to win and record what would have been a second home win of the season.
Martinez said: "In many ways it sums up our season. The performance was as good as it gets but we've had too many games similar to [this one].
"If we perform like we did [on Saturday] we'll get enough points."
Wigan face four of the Premier League's top seven teams in their next five matches - a home game against Manchester United comes in the midst of trips to Liverpool, Chelsea and Arsenal - but Martinez remains undaunted by the challenge ahead.
"I know that we are a group that can cope with the frustration and we can perform game after game," he added.
"We haven't had the rewards for good home performances. It's unfair the players haven't had the credit for the good things they have done on the pitch."
However, he admitted to feeling frustrated by his side's inability to keep just a fourth clean sheet of the season as they allowed Albion back into the game from a set-piece.
"Scoring the first goal is always the hardest moment in the game - and we got that," he said. "Then we got heavily punished.
"It was a game to win by three or four goals. That's how dominant we felt. A simple set-play cost us but we restricted West Brom to very little.
"The disappointment is that we could not keep a clean sheet when, in many ways, we deserved that. It is a tough game to swallow."
Martinez's opposite number Roy Hodgson conceded that West Brom were lucky to leave the DW Stadium with a point.
"If you look at the chances created and the balance of play, Wigan had the better of it and if any team was going to win, they deserved it," he said.
"I've seen us play better but we showed a lot of grit and determination. Everyone had this down as a must-win game for them so it was creditable that we showed we wouldn't give in."
Hodgson also felt that referee Michael Oliver showed common sense in not sending off Youssouf Mulumbu for shoving James McArthur in the back after a heavy challenge.
"I thought it was a storm in a teacup," stated Hodgson.
"He reacted as he was being kicked. But I think it's sad if people want to send players off for that. If you apply the letter of the law, it would be red.
"But, with the letter of the law these days, if it's applied, we'd be lucky to finish off with seven-a-side."
