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 tonight'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 we played in the Champions League semi-finals," he pointed out.
"At Real Madrid, I won the Super Cup, lost the cup final and went to the Champions League semi-finals. These are my third seasons, so look at 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, the Portuguese would be leading 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 tonight'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 have started badly. (But) you have just to go back three months, we were the best team in the country. 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."
Mourinho thinks people are looking for issues which are not present.
"It's quite sad that many people try to find problems where problems don't exist," he said. "When people aren't getting success, you cannot expect smiles."
Chelsea will be without striker Radamel Falcao due to a tendon problem, but playmaker Oscar is available following a knee injury.
