But Benitez says he has no fears about the experienced England duo easing off and just going through the motions as their contracts tick down.
He said: "They are very good professionals, doing their best. I do not know what will happen, but they will focus on doing their jobs.
"I talk with them every day. I had a conversation with Frank Lampard last week and he was quite positive.
"He is a professional and has experience and knows he has to keep working hard and I will make decisions and we were fine.
"Ashley? He is fine, too. We joke every day."
