Ben Foster replaced injured Boaz Myhill during West Brom's 2-1 FA Cup fourth-round win over Birmingham City

Ben Foster says new West Brom manager Tony Pulis has introduced a "brutal" regime, but believes his methods will get the best out of the players.

Pulis is unbeaten in his first four games since replacing Alan Irvine, including Saturday's 2-1 win over Birmingham in the FA Cup fourth round.

Goalkeeper Foster, 31, believes the Albion squad have been given a wake-up call by the 57-year-old.

"It is brutal, but I love it. I think it's fantastic," he said.

"I would say he is just on to players a bit more. Nobody really gets away with anything now.

"He lets nobody have rest days or slack off - nothing like that.

"If I was a manager, I would be like him. You've got to treat football players like kids sometimes. If you give them an inch, they will take a mile - it's amazing."

Foster, who replaced Boaz Myhill in the second half at St Andrew's after the deputy goalkeeper's finger injury, said former Stoke City manager Pulis had not mellowed.

"Definitely not. He's the same old Tony Pulis and I think he's great, I really do," the England international said.

"He's so professional, so thorough and he thinks everything through down to the minutest detail."
