Sir Alex Ferguson has thrown down the gauntlet to Barclays Premier League champions Chelsea and vowed: "We'll be back".
Manchester United lost this season's title by one point to the Blues, who could go on to complete the domestic double if they overcome Portsmouth in Saturday's FA Cup final.
Ferguson has only the Carling Cup to show for his efforts this term, but he is ready to go all out to wrest the championship back from Stamford Bridge and chalk up a record 19th title for the Red Devils.
"It was a disappointment but you can agonise over these things and I'm experienced to know you can't win them all," said Ferguson.
"What you try to do is recover from every defeat and try to regain the upper hand next season.
"It's a challenge. A few years ago it was Arsenal, then it was Chelsea, and each time we've managed to raise the bar at our football club - and that is exactly what we are going to do next year."
Ferguson is showing no signs of slowing down at the age of 68 and is as motivated as ever to bring more silverware to Old Trafford.
"I'm at the right club," he added. "It's easy to be motivated at Manchester United simply because of the great players we've had over the years.
"Also what drives me on is expectation. In the modern world, once you achieve some success, the next step is to deal with the expectation and it's very difficult.
"But it's a challenge and if you don't want that challenge you won't survive. And I've always accepted the challenge."
