Benitez was speaking after their 3-1 Coppa Italia win over Atalanta.
He declared: "I am sure 100 per cent that the President will do something this week. I am certain of it. Tomorrow? We still have a few days to work and sort things out, but we'll do at least one or two moves this week.
"I only talk about my own players, not those who are at other clubs."
