Carlos Corberán believes Albion didn't manage the first 15 to 20 minutes of the second half well enough on Saturday afternoon at Deepdale.
The Baggies were held to a 1-1 draw by Preston North End in the Sky Bet Championship, with Karlan Grant opening the scoring inside 20 minutes before Emil Riis' equaliser ten minutes into the second period.
Corberán's men performed well in the first 45, but the hosts came out firing after the break and deservedly found a leveller.
The boss says it's a pity his team couldn't prevent Preston getting back into the encounter and admits Albion could have much offered more in Lancashire.
Carlos said: “It’s one point that of course is not enough to be in a better position in the table. It was necessary to add more than just one point today.
“In general, the first half was more positive than negative. In the second half, we suffered too much in the first 15 minutes until we found a way back into the game.
“We didn’t find the right solution to the set-pieces and the second balls. They have created difficulties which we should’ve managed better. We have lost the option to win the three points in these moments of the game.
“In the second part of the second half we recovered the feeling that we could attack, but in general, the first 15 to 20 minutes of the second half were the most difficult moments of the game.
“We expected them to come out strongly at the start of the second period because every time that you compete well, especially away, the opponents need to provide a reaction.
“They adapted some things, but we need to have an immediate reaction to anything that can happen.
“Football for me is not about fair results. It’s one game where we should have competed and performed better to get a better result.
“I always analyse games. We are frustrated that we didn’t manage the first minutes of the second half better. We know we need to improve and it’s a pity we didn’t manage these key minutes of the game.
“When you step on to the pitch you want to win the three points. We are disappointed but will take the responsibility ourselves. We know we have to make more things happen to win more games.”
