West Bromwich Albion boss Slaven Bilic admits his must maintain their intensity for 90 minutes after falling 3-0 to Leicester City on Sunday.

The newly promoted side were blown away with three goals in the second-half at the Hawthorns.

Speaking after the game, Bilic said: "Leicester showed their class. They are a good team. We knew that before the game.

"I wanted to win this game and we approached this game this way. I was delighted with how positive we were, how we passed the ball and how we were getting in good situations.

"After the goal, we didn't give up, but it wasn't the same mentality.

"That's the only thing I told the players in a negative way.

"We can't do that and the players didn't deserve that. We have to stretch the intensity to 90 minutes plus.

"It wasn't Leicester playing the first-half in the same way as you would in a friendly game. No. It was us playing well.

"Every goal you score gives you a boost and every goal you concede gets you down, but it can't be this much. It was a lot.

"The message will be to remain upbeat. It is just one game and Leicester are a good team.

"We're going to work on it.

"We've been punished for not raising the levels."
