Left Winger - Neymar
Neymar is one of numerous star-studded players on PSG's expensively assembled roster. But the Brazilian hasn't yet hit his stride this season. He has scored just once - from the penalty spot - in five games across competitions.
The 29-year-old did play ninety minutes in PSG's Champions League opener against Club Brugge. But he turned in an underwhelming performance as the Ligue 1 giants were forced to split points on the night.
Nevertheless, the 2015 Champions League winner is expected to make his second start in the competition on Tuesday.
Centre-Forward - Kylian Mbappe
Kylian Mbappe is one of the best young players in the game at the moment. Despite being close to joining Real Madrid, Mbappe has stayed put at PSG and has fared well for them this season.
Recently, the 22-year-old registered his 150th Ligue 1 goal contribution since making his debut in the competition almost six years ago. Mbappe has scored four goals and provided three assists in the league this season, but is yet to open his account in the Champions League.
After sustaining an injury against Club Brugge, Mbappe will look to impact the game more against Manchester City and help PSG get their first UCL win of the season.
Right Winger - Lionel Messi
Lionel Messi, widely regarded as the best player to have graced the game, arrived at PSG on a free transfer this summer.
Despite his prolific form in international football, the 34-year-old is yet to open his account for the Ligue 1 giants. Messi has played three games across competitions for his new employers, including one in the Champions League.
After hitting the woodwork twice, Messi will look to score his much-awaited first goal for PSG when City come calling on Tuesday.
