Clarke is delighted to be able to call on the ex-Sunderland star.
"I won't have to motivate Stephane," he told the WBA website.
"He's got a new club, he's got a new challenge.
"You can see every day in training he's excited about the prospect of playing here.
"He's looking forward to the game at the weekend and I don't think it would matter who he was playing against - he would still be looking forward to the game at the weekend."
