Manchester United manager Sir Alex Ferguson believes billionaire neighbours Manchester City will simply keep on spending until they win something.
Speaking ahead of Wednesday's Manchester derby, Ferguson claimed City could easily spend another £100 million on five or six players if they need to boost the quality of the squad.
United, the only unbeaten team in the top flight and lying second in the Premier League, travel to Eastlands with a three-point lead over their rivals and there is more than just bragging rights at stake now that City are genuine title contenders.
"It does put an edge on [the game]. I don't believe there's any question about that," Ferguson told Inside United.
"We know the kind of money they're spending - they've bought another five or six players in the summer and they'll keep doing that until they win something. You know that's going to be the way it is and you have to deal with it as it comes along.
"They're up there [challenging for the title], and you can't wait until tomorrow when there's something there today. I'm sure they're thinking that way themselves."
