Queens Park Rangers chief executive Philip Beard has revealed the club is not prepared to accept another relegation scrap.
The recruits included several big-name players and Beard told London 24: "We haven't made the investment of this summer to simply compete at the same level as last season.
"The investment has been made so that we feel we are a club that can compete against – and beat – every club we play.
"We all believe that the squad we have now should be able to get stability in the Premier League – not fighting for survival."
Beard played down fears QPR had spent beyond its means, especially on wages.
He said: "Some clubs have spent £12 million ($18.5 million) or £15 million ($23 million) on one player. You would struggle to get that sort of number for all the players we have signed.
"What we have done is strike a balance. I have looked at it long and hard, and there are some very talented young players we have brought to the club who I think will be available for a long time to come."
The latest transfer window was QPR's third in a row that witnessed a huge influx of players but Beard was confident such a turnover would not be repeated.
He also defended the decision to sign goalkeeper
"The club now has two very strong goalkeepers, and Mark will decide which one plays when," he said.
"The best teams have strength in every position."
QPR's transfer activity included
The controversial midfielder is currently in the midst of a 12-game ban for his violent conduct in the final game of last season but he has managed to charm his new team-mates.
"It's maybe the case that, on the pitch, he is different, with another kind of desire, another kind of commitment, another kind of aggression.
"But, away from it, he's truly a good person."
