Darren Moore guided Albion to another win to extend their slim chances of avoiding the drop after a thrilling 1-0 victory over Tottenham Hotspur.
Albion were heading for relegation until the 92nd minute when Jake Livermore forced the ball home to give the Baggies the victory they needed to extend their Premier League stay for another week.
If results go their way, Albion can now avoid the drop with victory over Crystal Palace next weekend after Moore's earned his first three points at The Hawthorns.
"The place was electric today. We thank the fans. They were our twelfth man today," he said.
"We've come together as a group and we're just working. The hard work is paying off. We'll just move on to next week's game. We can't do anything about what happens elsewhere," said the fans' favourite Moore.
"It's another good three points for us. It was a really good performance by the boys. They gave everything today.
"We spoke about commitment, desire and courage. They've shown that since I've stepped into this role. They've been second to none.
"I'm so pleased, again, for everybody connected with the football club. The message is clear again - when we all come together, we can achieve a lot."
