West Brom next face Aston Villa after the international break.
"I don't think you can linger and look backwards for too long in the Barclays Premier League," said Clarke to the WBA website.
"We don't get some of the players back for a while and our next game is against Villa, which is a great game at home.
"We'll take all the good bits from the Chelsea game and look forward to what should be a good derby game.
"It's not until a week on Monday, so at least when the players come back from international duty, we'll have three of four days together to prepare for the next game."
