"The players had a go and in truth we were maybe close to winning it at one point, but in the end we've ended up losing quite heavily."
West Brom manager Roberto di Matteo praised his team's lethal finishing, saying: "There were some excellent goals. We were very clinical, which has been missing in the last few weeks from our game.
"I thought we played some fantastic football, we didn't show any fear. We showed a lot of courage to come here and play the football we did.
Di Matteo hails 'incredible' West Brom
"We rode our luck a bit at 2-1 and our keeper made some great saves to keep us in the game. But the quality of our play and the quality of goals gave us our advantage."
The only downside for the Baggies was the late sending-off of Mulumbu for two bookable offences. The defender received his first yellow for over-celebrating his goal and moments later was booked for a challenge on Steven Pienaar.
"He needs to learn a bit, but I think the second yellow card was a bit harsh. I don't think he touched the opponent and I think he got the ball as well," said Di Matteo.
"If we have yellow cards for those challenges we should have 20 in every game."
