Blackburn midfielder David Dunn has warned big-spending Manchester City that Rovers will "kick lumps" out of their star players on Saturday.
City, who have spent almost £100m on players this summer, begin their Premier League campaign at Ewood Park.
"It's important we do our best and kick lumps out of them - fairly of course," Dunn said.
"We must be strong and organised. The main thing is we will have to be really aggressive and knock them about a bit."
He added: "That's what the manager will be asking from our lads. We have to make Ewood Park a place no-one wants to come to again.
City manager Mark Hughes, who left Blackburn to take charge at Eastlands in June 2008, is expected to field several of his new multi-million pound signings on the opening day of the new season.
While former Rovers striker Roque Santa Cruz is not in contention to face his old club because of injury, Carlos Tevez, Emmanuel Adebayor, Gareth Barry and Kolo Toure are all expected to feature.
Dunn feels they could need time to settle, and hopes Blackburn can take advantage.
"I think it is a good time to play City," he added.
"Unfortunately we don't have the same resources. But what we do have is an even level on that pitch and as soon as the lads cross the white line the money doesn't really matter. It's about how much you want it."
Blackburn boss Sam Allardyce also feels Hughes might struggle to bed in his new players into his expensively assembled side.
"A whole group of new players, or five or six new players, is certainly something that causes you a few problems," Allardyce explained.
For us it's about trying to spoil their party, being that they think that they can come to a place like Blackburn Rovers and beat us comfortably with that kind of spending

"I've suffered it in the past myself at previous clubs where nine or 10 new players have come in and we've tried to play them all at the start of the season.
"While they have been very good players, there has been some disruption there.
"I hope that might be the case against Manchester City on Saturday. If it is, then we have to try and take advantage of that."
Expectations are high at City ahead of the new season but Allardyce is keen to give them as difficult a time as possible in their first game.
"Everybody will expect success instantly at Manchester City, that's the pressure they have got to live with," he said.
"For us it's about trying to spoil their party, being that they think that they can come to a place like Blackburn Rovers and beat us comfortably with that kind of spending.
"We're certainly going to go all out to make sure that's not the case."
