Benitez believes the incentive to finish fourth and win the Europa League applies not only to his players but any prospective new signings.
"Players want to win trophies and want to finish in the top four," said the Spaniard, who has already agreed a pre-contract deal with Standard Liege forward Milan Jovanovic.
"The players know it is important to perform now for the future and they want to stay here so I think it will be okay.
"We are now in a situation where we have to move forward and try to bring the best from each player.
"It is not easy to stay at a very good level in a season.
"The main thing is we have some players coming back from injuries and if they are together and push together I am sure we will do really well.
"This club is a massive club so if we can progress in the Europa League and finish in the top four a lot of [other] players will be thinking whether to come here or stay where they are."
