Albion boss Sami Hyypia has vowed to stay angry if it brings the best out of his players.

The calm and collected Finn was unhappy with the first-half performance at Nottingham Forest, despite a commendable 0-0 draw against the deposed Championship leaders.

Hyypia told The Argus: “What I say to the players is between me and them but I wasn’t happy with the first half and I gave them advice on how we could do better.

“When there’s a reason to get angry I get angry, I’m a human being.

“In this profession I think sometimes you have to get angry. I can do that as well and probably I’ll learn to be maybe even more angry in the future.

“I need to find a way to get more and more out of the squad and if that means I’m angry every week then I will be but we have a good group of players.

“They just need to understand we can’t give the opposition that luxury of playing the way we did in the first half.

“Everyone understood at half-time we didn’t do well and needed to step it up. That’s what we did in the second half.”

Striker Sam Baldock is a doubt for Cardiff’s visit tomorrow night after missing the stalemate in the East Midlands with a calf problem.

Hyypia said: “He felt his calf in training and he needed to stop. He had a little something there and it would have been a risk to play him so it’s better to rest him for one or two games than be out for a month.”
