Jose Mourinho says he has nothing to prove despite Chelsea's worst start to a season in nearly 30 years.
The Blues boss also bristled when it was suggested he had an issue at staying with clubs for the longer term, countering the suggestion his third season was when everything goes wrong.
"I have nothing to show, to anyone. Nothing," Mourinho said.
Speaking ahead of Wednesday night's Champions League opener with Maccabi Tel-Aviv, Mourinho reeled off his achievements in his third seasons with Chelsea and Real Madrid; he only had two terms at Porto and Inter Milan.
"My third season at Chelsea, the first time, I won the FA Cup and the Carling Cup and I played the Champions League semi-finals," he added.
"In Real Madrid, I won the Super Cup, I lost the cup final and went to the Champions League semi-finals.
"These are my third seasons, so click Google instead of asking stupid questions."
Mourinho, who is in the third season since his return in June 2013, last month signed a four-year contract extension after repeatedly stating his wish to manage Chelsea for some time.
Asked about building a dynasty, he added: "It's the first time I'm going to do that, so I don't have experience in that."
Mourinho has not experienced a start to a campaign like this one, either.
Had Newcastle beaten West Ham on Monday night, Mourinho would be presiding over a team in the relegation zone, having lifted the title in May.
He cannot put his finger on the seismic change which has overcome the side as they seek a first home win of the season and second victory in all in Wednesday's Group G contest. But he pointed to his side's calibre.
"When we say business as usual, it's true. With one difference: we are not happy," Mourinho said.
"We start so bad. (But) you have just to go back three months and three months ago we were the best team in the country, the best manager and the best players. We are not happy, but we know what we are.
"Nobody can steal what we are, nobody can steal our trophies, nobody can steal our history. We know what we are: champions of England."
Reports of sour faces at Chelsea's Surrey training base are natural after results, said Mourinho, who thinks people are looking for issues which are not present.
"It's quite sad many people try to find problems where problems don't exist," he said.
"When people is not getting the success that you work for people are obviously frustrated and not happy. You cannot expect we are all smiles, laughing and jokes.
"Confidence levels... especially people used to winning all the time. When you don't, it's a strange feeling.
"Fights, no fights, I don't think it's important. But if it happens sometimes, between people that like each other very much, I don't think it is a drama, but we didn't arrive in the situation."
Chelsea will be without striker Radamel Falcao due to a minor tendon problem, but playmaker Oscar is available again following a knee injury.
Mourinho plans to make changes, despite anticipating debate as some of his established stars, notably Branislav Ivanovic and Cesc Fabregas, have struggled to regain their form of last season.
"If I leave out John Terry, it's because I have a problem with John Terry," said Mourinho, who also used Cesar Azpilicueta and Fabregas as examples.
"I cannot be worried about what you say, what you write.
"Yes, I'm going to make a couple of changes, because I have to try a couple of different faces."
Mourinho is looking for a strong start to the Champions League in a week when Arsenal travel to Stamford Bridge.
He said: "Yes, (Maccabi Tel-Aviv) can beat us, but at the same time we also know we are a better team. We have just to prove that in the game. A very big result is three points."
