When asked if City are under pressure at the CWC, Heskey said: "Yeah, 100 percent. City have to win or give everything to get as far as possible, for the financial side, too.
"They’re buying all these players. They're getting all these players coming in, so this would actually help them as well. They've just got Ait-Nouri from Wolves, they've got Cherki coming in from Lyon, so you've got to really pay for all this. So I'm guessing they've really got to have a go."
He added: "Nothing will happen to Pep if City struggle at the Club World Cup, to be honest, even if they’ve had a rough year up until this point.
"Let's be honest. I wouldn't say he's bulletproof, but he's not far off. The thing with Pep is that he’s just brought so much to Manchester City, to the club. He’s brought so much to the Premier League and to the country, too.
"So the players need to give everything, but I don’t see any pressure on Pep if things go wrong in America."
