Flying winger Matt Philiips has called for Albion to bounce back immediately after the Baggies' 1-0 defeat to Middlesborough.
Albion looked to be heading home with a point until Daniel Ayala scored in injury time after the visitors had failed to clear a routine free kick.
Phillips admits the last minute goal was hard to take, but believes it's just one of the ups-and-downs his teammates will face this season.
He said: "We will dust ourselves down and go again in the cup on Tuesday night and again next weekend. We’ll probably go out with a strong side and keep going with what we’ve been working on. Then we’ll focus and build for next Saturday.
“The gaffer has told us to just keep going - we are a work in progress.
“We had the highs last weekend and this is a low.
“The whole squad is vying for a place in the starting line-up and it’s up to the ones in the team to put in performances.”
