And while Fernando Torres might be pleased to see his old Liverpool boss, others who have played under the Spaniard do not remember him quite so fondly.
Former Inter defender Marco Materazzi was "devastated" when Benitez replaced Jose Mourinho, who shared a joke with another former Nerazzurri star - City defender Maicon - at the new Chelsea boss' expense.
"Your friend Benitez is going to Chelsea," the Brazilian said to Mourinho, according to La Sexta.
The 49-year-old responded: "The fat one? Well then Materazzi should be his assistant."
