Valérien Ismaël says his side’s performance against Middlesbrough lacked “consistency” as they were made to settle for a point on Saturday afternoon.
Josh Coburn put the visitors ahead in the first 45 but the Baggies hit back after the break when Grady Diangana fired in his first goal of the season.
But despite the equaliser, the boss admitted he was left “frustrated” by the display at The Hawthorns.
He said: “It’s a frustrating afternoon.
“Nothing went in the right direction. We lost Jake Livermore in the morning and then we lost Matt Clarke after about 30 seconds.
“We needed to change the plan from that moment.
“It took away the rhythm. It’s difficult when the opponent has a low block and tries to waste time.
“We needed to be patient but we also needed to put the quality in the game.
“We didn’t play with consistency. We played well for ten or 15 minutes and then the next ten or 15 minutes was weak and poor.
“We need more quality in the last third. The last pass, the cross or the final touch to finish the job. We didn’t have that today.
“This is the result of a performance like Saturday. We’ve only drawn the game and we wanted to win.
“From one side, it’s good that Grady scored his first goal and we took a point.
“Saying that, our performance throughout the 90 minutes wasn’t enough to take the win.
“We were too hectic and we needed some calmness in the attacking areas.
“We showed the comeback mentality in the game. The momentum was with us for a bit, but then Middlesbrough managed to play in our half for a while and win a few free-kicks and corners which halted our momentum.
“Our performance didn’t have consistency.”
