Jose Mourinho does not fear he will be sacked by Real Madrid even if they fail to qualify for the last eight of the Champions League.
The Spanish leaders take on CSKA Moscow on Wednesday with the tie delicately poised following a 1-1 first leg draw at Luzhniki Stadium in Russia.
The pressure is on Mourinho to deliver European success having won the prestigious trophy with Inter Milan in 2010 following a 2-0 success over Bayern Munich at the Santiago Bernabeu.
Real are currently ten points clear of Barcelona in the race for the Liga title and Mourinho, who has been linked with a summer return to Chelsea, does not think failure against CSKA will affect his position.
"My future won't be decided by Wednesday's result, unless the club fire me if we don't qualify," said Mourinho. "But from my point of view it (result) won't change a thing.
"The first leg was a complicated result which leaves things quite open. Looking to tomorrow I'm more afraid of the game, which can produce all sorts of surprises."
However, Mourinho is confident his team will get the job done on Wednesday night and says they "fear nothing and no one" in their bid to bring the Champions League trophy back to the Bernabeu for the first time in a decade.
He said: "Our confidence is high and we fear nothing and no one. It's always difficult in the Champions League because you face the best of each country, but we're not obsessed about anything and have no inferiority complexes of any sort."
Should Mourinho's troops have needed any reminding that there is no room for complacency in football, it arrived in the third minute of stoppage time in the first leg when Pontus Wernbloom made them pay for their profligacy by netting an improbable equaliser.
"Football is treacherous in its nature and always has room for surprises," Mourinho continued.
"The best team doesn't always win and the 1-1 score of the first leg gives us every reason to think the match will be difficult.
"Russian teams are always strong and know how to defend. I have experience against them and am perfectly aware of the difficulties we'll face, so I try to make my men aware of them also.
"There are no miracles in football, but there are surprises. If CSKA win it will be because they played a very good game or because we played badly."
Cristiano Ronaldo's first-half strike handed Madrid the lead in the first leg and the Portugal winger has called on the Bernabeu faithful to play their part on Wednesday night.
Despite his 40 goals in all competitions for the club this season, Ronaldo's lack of popularity with some sections of the Madrid fans remains a problem.
However, the former Manchester United player has reported an improvement in his treatment in recent weeks, and knows the backing of the supporters will be key as Madrid chase both domestic and European glory in the final weeks of the season.
"I've heard the crowd sing my name in the last few months and I'm happy for their affection," Ronaldo said.
"We notice when the atmosphere is good during a match. I would like to ask fans to keep supporting us so that we win something this year all together."
Ronaldo also played down speculation over the future of Mourinho.
"He is going to continue," Ronaldo said. "He is going to continue with us."
Madrid will be without the injured Angel di Maria and Fabio Coentrao, while there was no place in the matchday squad for Hamit Altintop, Ricardo Carvalho and Jose Callejon.
CSKA have been boosted by the return of talismanic goalkeeper Igor Akinfeev ahead of the match.
Akinfeev has been sidelined by a knee problem since August, and although the match is likely to come too soon for the 25-year-old, Russian media report that his return has come as a lift to the whole squad.
Back-up goalkeeper Sergey Chepchugov is likely to retain his place on Wednesday night, and he admits to being relaxed about the task ahead, telling Sport-Express: "I am in a good mood and we are working hard."
CSKA coach Leonid Slutsky, who is sweating on the fitness of Japan international Keisuke Honda (thigh), admits that he side are huge underdogs ahead of the return.
"There's a low probability [of victory]," he told Sport-Express. "But sometimes miracles happen, and we hope that we will be able to produce a miracle like that."
