The high-profile capture of former Leeds favourite Gareth Ellis, along with half a dozen other major signings, has sent hopes in west Hull soaring and Gentle knows an improvement on the sixth-placed finish in his first year at the KC Stadium is the minimum goal.
"Obviously we'd like an improvement on last season," Gentle said. "I think last season was probably a fair indication of where we're at. We've got higher aspirations than that. We've a pretty fair squad I believe."
He added: "We've had seven signings. We're a lot quicker, we're bigger and we're definitely a lot smarter.
"The players I've had from last year know each other a lot better but the players we've brought in are smart players. So we're expecting to be there or thereabouts."
Joe Arundel, Daniel Holdsworth, Jason Crookes, Shannon McDonnell, Ben Galea and Paul Johnson will all make their Hull debuts against the Rhinos but Gentle accepts that most eyes will be focused on Ellis as he makes his return to Super League after a successful four-year stint in Australia.
Ellis turned down the chance to rejoin Leeds and was rewarded with the Hull captaincy by a grateful Gentle.
"He's a quality player and a quality person," the coach said of the seasoned England forward.
"He's just a great character to have around the place. He's slotted in great. He's naturally just one of the leaders."
