The Gunners took a point away from the Hawthorns yesterday.
"We knew we were playing a great team, but we did very well," admitted Congolese international Mulumbu.
"I think we had a great chance to score, Nicolas missed a great chance. We are really happy with point today.
"But we are a good team and now we need to focus on the next game.
"We're strong defensively and were waiting for the counter, but I think we missed a late chance to score and that's why we drew today."
