It's a repeat of last season's semi-final tie, which saw City prevail 4-1 on aggregate after two gruelling, high-intensity games of football.
But that was last season. This is a new match and PSG had a busy summer in the transfer market, which included the acquisition of Lionel Messi.
"It was last season," Pep Guardiola said. "They were a fantastic team and it was a tight game and now they have Messi."
