The former Liverpool boss has seen the Blues struggle in recent weeks but after maintaining third place in the league table, Benitez has insisted that key players returning to Chelsea's squad will ensure that they finish in the top four.
Benitez told reporters: "At the moment I am confident we can do it.
"We're in the top three at the moment, doing well. I have confidence that we have enough quality and, with the players coming back, we'll have enough options to manage the games, win more games in a row and be in the top four."
Benitez has won 10 of his 20 matches in charge at Stamford Bridge.
