West Brom boss Tony Mowbray has urged calm after their derby defeat to Aston Villa.
He said: "The Premier League is pretty brutal and people aren't interested in the performances, only the results.
"There will be negativity again after the Villa result but we will deal with it and hopefully get a positive result in the next game.
"It is a learning process for a lot of our players. You've got to keep your composure when you go chasing the game and a result. We've got to stick to our beliefs.
"At times certain individuals were in too much of a rush against Villa to get forward, which at times left us vulnerable."
