Manchester City assistant boss Mark Bowen believes the club's mega-rich new owners will change the face of European football as well as the domestic game.
The Abu Dhabi United Group's ambitious plans for City have already seen them sign Robinho for £32.5m.
"The owners are going to challenge the top teams not just in this country but in Europe over the next few years," Bowen told BBC Radio 5 Live.
"I'm sure we will get up a few people's noses over the next 18 months."
Bowen also warned that the changes at the club might mean fewer of City's promising youth team players make the transition to the first team.
City have established a strong reputation for developing their own players in recent years, with academy products Shaun Wright-Phillips, Micah Richards, Michael Johnson and Stephen Ireland all featuring in last weekend's 3-0 away win over Sunderland.
"It will be a natural progression over the next year or so with a number of players coming in," added Bowen.
