Clarke's big-name summer signing has yet to get off the mark in for the Baggies since arriving on a high-profile free transfer.
The French veteran faces a fight for his place with the likes of Victor Anichebe, Saido Berahino, Stephane Sessegnon, Matej Vydra, Shane Long and Markus Rosenberg but Clarke has no doubt it is simply a matter of time until the proven marksman comes good.
"Good strikers will keep getting in good positions and if they keep getting in good positions, the goals will come," said the head coach.
"That's got to be the mantra for any striker. They have got to keep getting into good positions.
"Victor is back from injury and ready to go and yes, it gives me a problem.
"Victor's back, Saido's playing well, there's Nicolas, Matej Vydra is available, Markus Rosenberg is there, I've got loads of options up front. It's a good problem to have."
Fellow striker Long is another whose season has not quite sparked into life yet, with the Irishman set to leave on transfer deadline day until a move to Hull fell through.
His difficult campaign so far took another twist this week when he criticised Republic of Ireland caretaker manager Noel King for leaving him out of their games against Germany and Kazakhstan.
Clarke shrugged off Long's social media outburst, though.
"It's a long 10 days if you go away and expect to play for your country and don't get selected. It can be disappointing," he said.
"I didn't see the Tweet so I don't really know. I wouldn't think there would be too many bad words in the Tweet.
"If he said he was disappointed not to be selected then I would think that's acceptable.
"I'm not going to tell another manager who to pick or how to run their squad. Players get selected, they go away and the manager in charge of that country will decide if they play or not."
