Moyes said of the former Manchester United striker: "We know he (Saha) has got that ability and that's what we are hoping to get from him.
"He's coming back from injury and we need to get him playing as much as we can."
And Moyes believes Marouane Fellaini will be better for his derby run.
"I thought he did okay," continued Moyes with evertonfc.com. "There were good bits of his game - but what hampered him was the early booking.
"The referee booked him after ten minutes and that made him realise he had to be careful.
"He is only 20 and still learning his way in the team."
