Slaven Bilić admits to feeling frustrated after watching his Albion side draw 2-2 with Charlton.
The Baggies twice went ahead at The Hawthorns but Josh Cullen’s late penalty rescued a point for the visitors in injury time.
And Bilić says he was baffled by the decision to award the Addicks a stoppage-time spot-kick.
“The first half, although we are winning it, is nowhere near the first half we wanted to play,” he admitted.
“They are a good side, they run a lot, they pass the ball well. They are very brave, young, enthusiastic and enjoying the season, but it doesn’t matter, we have to take care of it, we didn’t press, we gave them time to win the second ball, we gave them time to choose options when to play, they didn’t create a lot. They created one chance in the first half.
“We scored a great goal and then we had a chance with Darnell also but it wasn’t a good first half. At half-time that is what I said - we can’t play like this we have to put in the authority.
“Second half we were top. We were magnificent, excellent running off the ball, with the ball, with the ball. Before their goal we created three or four clear-cut chances from combinations and pressing.”
And the Baggies boss also reflected on the two refereeing decisions that impacted the game - Nathan Ferguson’s red card and the penalty.
“They had a spell of two minutes before the goal and they scored and then we get a red card,” he added. “Nathan is a young player. He goes there and it is nothing reckless, but he touched the ball a little bit but not enough for the referee, not to give him an option to give him a red card. In that challenge there was nothing malicious.
“After that, although we were with ten men we defended really good, we attacked them really good and from one of those attacks we scored the goal. It wasn’t all them afterwards. They had ball possession but we defended excellently, not in the box also, outside. We kept counter-attacking and keeping the ball and then you see six minutes. Then to give that kind of a penalty in the 90th minute, as you say in England, it is beyond me.
“I know it is hard for a referee but I went in as I needed a chat and I said I know it is hard for you but this is an unbelievable decision. I have 11 players who were fighting for their lives and they deserved to win the game today. To take it away from them like that, it is unbelievable to be fair.”
