Doncaster Rovers Belles boss Glen Harris admits he needs to sign new players if his team are to challenge in Women's Super League One next season.
Harris said Sunderland, who finished fourth in their debut campaign in WSL1 this year, were a good example of how to recruit wisely.
"We need to strengthen," Harris told BBC Sport.
"The reality is we have a good core of players here that can obviously play at Super League One level and there are some that have played at that level.
"But Sunderland have shown what you can do. They also brought players in, so we need to bring three, four, five players in to actually strengthen the squad."
Doncaster's 4-0 win against Millwall win on Sunday was not enough to secure the WSL2 title, as they were pipped to first place by Reading on goal difference.
However, the club are set to offer a number of players full-time contracts ahead of next year and are currently building a new training facility.
Winger Sue Smith echoed her manager's thoughts and said the new set-up would help attract new faces.
"We have a good squad but we probably need to add a few players and I think the fact that we're going training full time next season is important," she said.
"We want to go up there and challenge, we don't want to just be a yo-yo team."
However, Harris insisted the calibre of any new potential signings would be vital.
"They've got to be better than what we've got, that's for sure," he added.
"We're not going to go second best, we're looking for better quality players."
