Derek McInnes says he will need to make changes to his Bristol City squad over the summer in order for them to avoid the drop next season.
City confirmed their Championship status on Saturday with a 2-0 win over Barnsley at Ashton Gate.
"With the situation we've been in, I think that would suggest there's work to be done," manager McInnes told BBC Radio Bristol.
"It's a big summer and we need to try and recruit well."
He continued: "I know where this club can be and I don't want to be part of a relegation battle next season.
"We need to make sure that when the players are doing a lap around the pitch at the end it's because we've had a successful season, not just because we've staved off relegation.
"It's an important period for the club and we don't want to be fighting this again. Hopefully with the right additions we can build a squad which is competitive and win more points than we have this season."
McInnes took over at the club in October when they were bottom of the Championship, and inherited a squad mainly built by former managers Steve Coppell and Keith Millen.
But with several first-team players out of contract in the summer, most notably former England goalkeeper David James and club stalwart Louis Carey, chairman Colin Sexstone says there will be the budget to expand next season.
"As a club we've always supported the manager and there are a few players out of contract," said Sexstone.
"Derek has to decide, along with us, which ones aren't going to be offered contracts and which ones are.
"I'm sure he'll come to us with targets for next year and we'll look at that as sensibly as we can.
"Potentially there's quite a few going out and I'd expect to see a number of new faces over the summer."
