DARREN Moore rued a lack of 'cutting edge' as Albion were beaten 2-1 by Bolton Wanderers on Saturday.
The Baggies enjoyed the lion's share of possession against the Trotters, firing 20 shots on their opponent's goal. But strikes from set-pieces either side of a Harvey Barnes stunner gave the visitors all three points on the opening day.
Darren said: "It was very frustrating in the end against difficult opponents.
"We huffed and puffed, got into some good areas of the pitch but probably could have been more effective.
"We came up against a disciplined, resolute rearguard. We know how difficult that style is to play against because we've adapted that over many seasons in the Premier League and got results against very good teams.
"It's a difficult system to break down. But it shows that when teams come up to The Hawthorns we've got to find ways of breaking them down.
"We had plenty of possession and I was happy with that. We need to work a little bit more on having that cutting edge in the final third.
"The disappointing thing is losing two goals from set plays. That's never easy to swallow.
"But I don't want to take anything away from Bolton. They came with a game plan, stuck to it and got three points."
Albion have an immediate opportunity to put things right, travelling to Nottingham Forest on Tuesday evening.
Darren added: "You don't want to lose your first game at home. But we've got to move on very quickly.
"In this division, every team is capable of beating every team.
"These are the kind of things we're facing this season - plenty of hurdles. It's about preparing for one game at a time."
