"It is a process of staying true to your profession and that is what I will do and I hope my players do the same," he is quoted as saying by Sky Sports News.
"We will go to work next week to try and get ourselves a win and that is all we can do.
"In terms of building on that performance, there is something there from the game against Watford to build on."
West Brom will look to arrest their dismal run of form when they host Leicester City at The Hawthorns on Saturday.
