Sanches is on-loan at Swans from Bayern Munich and currently carrying an injury knock.
Clement explained: “I don't think it's surprising. If you've come off the back end of a season where you've hardly played, pre-season a similar situation, a lot of uncertainty about what he's going to do, he comes in and straight into Premier League high intensity football.
“I don't think it's unusual that he's picked up a couple of niggles. It's not a serious injury. I think normally, seven to 10 days and they're back in action."
