Steve Clarke has called for his West Bromwich Albion players to maintain their focus in this weekend's Midlands derby.
The Baggies face Aston Villa on Sunday, with Clarke expecting a hostile atmosphere at Villa Park.
Clarke told BBC Sport: "It is going to start frantic, it is going to be passionate, the crowd will be really involved.
"It is important for the players to have a cool mind."
West Brom are in fourth place in the Premier League table after making an impressive start to life under Clarke, recording victories against Liverpool and Everton plus earning a credible draw at White Hart Lane.
