Carlos Corberán says his players must aspire to deliver complete performances rather than playing well in spells.
The Baggies were held to a goalless draw on Saturday at The Hawthorns by a stubborn Millwall team, their second one in seven days.
The away side could’ve taken the lead going into the break, but Alex Palmer made a fine save to deny Zian Flemming from the penalty spot.
In the second 45, Alex Mowatt and Brandon Thomas-Asante saw efforts hit the crossbar, while Jayson Molumby and Matt Phillips were also unable to find a way through in what was a much-improved showing from Carlos’ men following the interval.
And the boss says he believes Albion deserved all three points, but admits his group have to find a way to compete at their best level for longer periods in fixtures.
Carlos said: “If you look at the statistics of the game, we were certainly doing a lot more than them to win that game.
“The only thing that we can regret is that we didn’t do these things for the full game.
“We showed a reaction in the second half and it was a reaction we had to show, especially after they missed the penalty. That’s the positive thing.
“The negative thing was part of the first half. We didn’t compete well enough in the game, in the 50-50 balls, in our defending or in our attacking.
“It was a poor beginning to the game for us.
“After they missed the penalty, we reacted and started to show more competitiveness. The second half was then a completely different game.
“We had a lot of scoring possibilities, but unfortunately we couldn’t score. We hit the post twice and we had a few more chances too.
“We were not clinical enough in the last action of our attacks and that could’ve been the difference between drawing and winning.
“We reduced any type of opportunity for them to score and we defended much better as a team after the break.
“Now our main focus is not just to keep a clean sheet. It’s to replicate our second-half performances against Bristol City and Millwall, and make sure we perform like that for the full 90 minutes.
“If we were to do that, we would give ourselves a much better chance of winning games.”
