Luiz Filipe Scolari says Chelsea's next opponents Wigan will be quaking in their boots in anticipation of the Blues' arrival.
Chelsea make the first of their seven Premiership trips to Lancashire this Sunday, full of confidence following their opening-day demolition of FA Cup holders Portsmouth.
Asked if champions Manchester United would be scared by the 4-0 win, new boss Scolari replied calmly: "No. Because Manchester is not our opponent next week, Wigan is.
"Maybe Wigan will be scared."
Chelsea have a 100 per cent Premiership record at Wigan's JJB Stadium, although on two of their three visits they left it until the last minute to score the winning goal.
Adding to Chelsea's confidence will be the news that John Terry will hold down the job of England captain for the coming World Cup qualifying campaign.
Although Scolari is not pleased about his preparations for the trip north being interrupted by last night's England friendly against the Czech Republic.
"For a few days the players go off to their international teams. It is frustrating. But these are the FIFA dates," he said.
"When they arrive back, we expect they will be in good condition. And they we will do some training.
"This is what a club coach expects."
However, the former Brazil and Portugal boss is philosophical, having seen both sides of the deal.
"Because I have coached national teams, I know the problem," he said.
"The coaches for the national teams need two days for training: Monday and Tuesday.
"It is difficult for the national team coaches.
"And when the players come back, we will make some plans for the (Wigan) game.Its not a problem for us." Scolari is expected to travel to Nyon in Switzerland next Thursday to find out Chelsea's fate in the Champions League group stages draw.
