Clarke, 48, who was introduced to the media as Roy Hodgson's successor on Monday, takes over at the Hawthorns following stints as an assistant coach at Chelsea, Liverpool, Newcastle United and West Ham United.

The former Scotland international insists he is ready to make the transition to manager after serving as an understudy to the likes of Jose Mourinho, Sir Bobby Robson and Kenny Dalglish.

"I think I will need to be a bit more selfish now I'm a head coach - I'll have to be very clear with my ideas," Clarke told the official West Bromwich Albion website.

"I will also have to be a bit more ruthless.

"When you're the assistant, you can be nice to almost everybody.

"But as a head coach, even though you want to be nice to everybody, at the end of the day, you can only pick 11 players plus seven substitutes.

"There is always going to be a number of players who are not particularly happy that they're not in the team for whatever reason.

"That's something I'll have to deal with - but it's something I'm comfortable with and ready for."

Clarke, whose first competitive fixture in charge will be at home to Liverpool on August 18, has pledged to excite the Albion faithful.

"I think my philosophy at any team I've coached has always been to try and get the ball down and play good football," he said.

"You want to entertain the public as much as you can, so if we can add some really good attacking football to the solid defence we already have, that would be an ideal scenario.

"I've always tried to entertain the public and this job will be no exception."
