Cahill scored in the memorable 3-0 victory in last season's corresponding fixture and the boss is delighted to have him back in the fray.
"He is a goalscoring central midfielder with drive and when you look at the goals he has scored for Everton in the past three years, he has been a big part of our success.
"This a big period for us. We gave the players a few days off last week after a difficult period and gave them a chance to relax. From Saturday, we have a lot of big games and need them fresh."
