Jose Mourinho is prepared to accept more short-term pain for long-term gain as he bids to revolutionise Chelsea's style of play.
Chelsea are without a win in four games - against Manchester United, Bayern Munich, Everton and Basle - ahead of Saturday's Barclays Premier League match with Fulham and on Wednesday lost a Champions League group game at home for the first time in almost 10 years.
It is unusual territory for Chelsea and for Mourinho, the club's most successful manager following a silverware-laden first spell at Stamford Bridge.
The self-proclaimed Special One has continually talked of an alteration in Chelsea's approach and the process is one which will continue, even though owner Roman Abramovich is not renowned for his patience.
"We want to change and we're going to change," Mourinho said.
"I agree we must have better results. I agree we are not the kind of club that is going to wait two, three, four, five years to have a team.
"We have to accelerate the process, but we are not going to change.
"We want this team to play in a certain way and that's the way we're going to work."
Mourinho, who is just a few months into a four-year contract, dismissed talk of a crisis.
He said: "Crisis of what? Syria? For me, no crisis, for me two bad results."
Mourinho has been tasked with achieving results, as well as overhauling the style, something which proved too challenging for numerous managers in between his spells at the club.
"The situation is clear," he added.
"I don't like the way Chelsea was playing in the last couple of years. The club doesn't like. We want to change.
"We have the players with the profile to change. We want to play a different style.
"The past is history, even my past. I always said I'm here like I've just arrived. "I don't want to be protected because of what I did here in the past. It matters absolutely nothing."
The Chelsea team of Mourinho's first spell was characterised by a physical athleticism and indomitable will; the current squad comprises a number of skilful players more suited to intricate play.
The potential of the Chelsea squad has been clear at times this term, including in the European Super Cup penalty shootout defeat to Bayern Munich, but Mourinho knows it will take time for his players to reproduce the display regularly.
"When I saw my team play against Bayern Munich I thought the team was brilliant and when you play like that against the champions of Europe, you think you can do it immediately," said Mourinho, before referring to tactics and selection of previous seasons.
"But I think it's also part of a process, this instability. We have work to do.
"I don't want central defenders playing in midfield. I don't want the team to play with a low block and play long balls to a lonely striker. I don't want to do that."
Mourinho went against his usual plan on the eve of a game by opting against a tactical session, instead emphasising fun.
Ramires is available following suspension, while there are no fitness concerns.
Wednesday's unexpected loss to Basle was met by a smattering of boos, but Mourinho is focused on progress through the season.
Mourinho said: "I'm worried because I lost. I'm worried because I don't want to lose.
"If we qualify, this defeat means just a defeat. Nothing else.
"We lost nothing. You like scrutiny and you like to compare things.
"We didn't finish third in the Champions League group. We didn't get relegated to the Europa League. And we didn't finish third in the Premier League.
"We lost one match in the Premier League, the other five contenders for the title, all of them lost a match, except Liverpool, who are top of the league.
"In the Champions League we lost a match that we cannot lose, but we were not relegated to the Europa League.
"It's not the way you start, it's the way you finish. You want to start good, go good and finish good. That's the perfect picture.
"But between starting bad and finishing well, or starting well and finishing bad, I prefer to start bad and finish well.
"If you like scrutiny, if you like to make comparisons, you have to wait."
