West Bromwich Albion boss Steve Clarke admits he needs to develop a "ruthless streak".

Clarke knows there's a big difference from being a trusted No2 to being the top man.

"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," said Clarke.

"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."
