Tony Mowbray revealed his disappointment and frustration despite Albion picking up their first point for five games against Portsmouth. The Baggies were completely dominate against the FA Cup winners in the first-half with skipper, Jonathan Greening, giving the home side the lead six minutes before half-time.
The Baggies again found themselves on top in the second-half however had to settle for a share of the points when Peter Crouch's deflected effort cannoned in off the bar two minutes before the hour mark.
Despite having England pair Jermain Defoe and Peter Crouch in attack, it was Albion who pushed forward for the winner with England No.1 David James making a number of saves to keep the Baggies at bay.
"I think we probably deserved a second goal in the first-half and yet it didn't come, which was potentially going to make the second-half more edgy for us," the Albion boss said.
"That happens when you haven't won for so long.
"Yet I thought we were pretty comfortable for the rest of the game.
"I can't remember Scott Carson making too many saves when they started pressing us.
"Ultimately, I think it was our inability to score a second goal when we were on top that probably stopped us getting three points.
"But saying that, credit to Portsmouth.
"It was a great strike by Peter Crouch which took a deflection and enabled it to dip under the bar for their equaliser.
"That's the Premier League.
"You could feel the quality Portsmouth have in forward areas.
"Jermain Defoe's movement was good and he's always a menace.
"Crouch is what he is and scored a great goal today.
"We didn't manage to get that second goal to get over the line and get the victory."
The point moves Albion within three points of escaping the relegation zone with a trip to 19th place Sunderland next up for the Baggies. Although moving a point closer to 17th position, Mowbray admitted his frustration at not bagging all three points.
"Getting off 11 points is a consolation, I suppose," he added.
"But it was a frustrating day for us.
"There were spells in the second half where we probably warranted a second goal.
"Yet you could feel the quality Portsmouth had.
"I think we looked a threat breaking away and yet the final little bit was not there - the decision to put yourself in the right position or the quality of the final ball.
"Did we create many chances in the second half when we should have scored?
"There were bits and pieces really but in the first half there were better chances to get a second goal.
"All that said, I don't think Scott had to make a save.
"Glen Johnson had one he put over the bar and Scott half-fumbled a cross. I think that was it from them generally.
"It wasn't a game where we were under any great pressure and yet again we didn't have the ultimate quality to finish them off."
Mowbray continued: "We want to win our home games but we're not too despondent.
"We were playing in the Premier League against a side who possess international footballers.
"We're more than capable of holding our own.
"We've just got to start turning some steady performances over the last few weeks into winning ones.
"We look forward to the next challenge, which is Sunderland away.
"We should go into that in confident mood.
"Our recent away performances have been very solid and we were a constant threat at Wigan.
"We had over 20 shots last weekend at Wigan's goal and hopefully we can start turning decent performances into points."
