The former Liverpool defender says Manuel Pellegrini needs a victory like PSG's over Chelsea to avoid the sack.
Former Liverpool defender Jamie Carragher has told Sky Sports that Manuel Pellegrini will have to beat Barcelona to save his job.
Manchester City take on the La Liga leaders having lost the first leg of their Champions League last-16 tie 2-1 at the Etihad, although they remain in with a chance after Lionel Messi missed a late penalty.
Chilean Pellegrini has come under increased pressure at City with them being eliminated from both domestic cup competitions, trailing Chelsea in the Premier League and seemingly on their way out of the Champions League.
Now, Carragher says that he must pull of the seemingly impossible in beating Barcelona in order to avoid the sack.
“I think he's got a big problem in terms of his job,” said Carragher.
“You only have to look at the owners and how they dealt with Mancini - a man who won the league. I think he won the FA Cup. Pellegrini won a domestic cup and the league in his first season. The exact same thing is happening. They're just drifting in that second season.”
The Sky pundit also says that Pellegrini must try to emulate what Paris St Germain manager Laurent Blanc did against Chelsea in the Champions League, engineer a win against seemingly impossible odds.
PSG managed to knock out the highly favoured Chelsea last week, despite losing Zlatan Ibrahimovic to a red card and going a goal down to Jose Mourinho’s side. The result has been credited to former France boss Blanc, who Carragher believes also saved his job with the impressive result.
“I think he's going to need a result like Laurent Blanc got,” added Carragher.
“I think Laurent Blanc saved his job at Paris Saint-Germain in that Chelsea game. I think he's [Pellegrini] going to need something like that on Wednesday night in the Nou Camp to stay there at the club.”
