Depth key to West Brom surge
The club currently sit fifth in the top flight after a 2-1 victory against Wigan on Saturday and after 11 games Clarke is growing increasingly confident.
Next up is a home fixture against Chelsea, who themselves have had a great start to the campaign, but Clarke feels he has the options available to keep up the fight for a place in the top six.
"We've got a lot of options in our squad which gives me some fantastic problems," Clarke told reporters.
"We play with intensity going forward and I was a little concerned the ones who played on Monday night might be carrying fatigue.
"I've got a quality squad and I have to use them. They know they're all valuable in terms of the club going forward."
The Scot made a bold call in dropping Peter Odemwingie, who had scored twice the week before in a win over Southampton, but the move paid off as his side secured their sixth triumph of the campaign.
The one concern Clarke will have is the absence of regular goalkeeper Ben Foster, who underwent an operation on a groin injury recently, and the manager is hoping to have the goalkeeper back sooner rather than later.
"Ben had a minor procedure but he's back and he's comfortable and hopefully he is going to start training next week," he said.
"He is doubtful for the Chelsea game but I still haven't ruled him out and beyond that we're hopeful."
