Lionel Messi's arrival at Paris Saint-Germain has left the club with the most frightening front line in the sport, but now coach Mauricio Pochettino is under pressure to deliver the glory on the pitch that their Qatari owners covet more than anything.
That means winning the Champions League, a competition in which PSG have reached the final and then the semi-finals in the last two seasons.
"We don't hide that it's our objective," PSG president Nasser al-Khelaifi said at Messi's unveiling when asked about the Champions League. However, he later told sports daily L'Equipe "it is not an obligation", despite the arrival of the six-time Ballon d'Or winner on a reported salary of 35 million euros ($41m) a year.
"We have a great team, but we have not won anything yet," he added.
PSG quickly emerged as the only obvious destination for Messi after the collapse of his new deal with Barcelona, and the player himself admitted the presence of Pochettino on the bench helped sway him.
Messi and Neymar, old pals from Barcelona, are delighted to team up again but there is speculation that Mbappe -- with just a year left on his contract -- is not happy about having to share even more of the limelight.
PSG do not want to let him go though, and Pochettino will have to ensure that fielding that all-star front three, as well as Angel di Maria, does not overly imbalance the team.
Former Real Madrid captain Sergio Ramos and Gianluigi Donnarumma are luxury options in defence and in goal. But Ramos is expected to make his debut for new club Paris Saint-German in September when he has fully recovered from a calf injury, the Ligue 1 giants said on Friday.
The Spanish defender is only likely to take the field "after the international break", probably for the home game against Clermont on September 11.
PSG won their opening game of the league season 2-1 at Troyes last weekend and now host Strasbourg on Saturday, when Messi is set to be paraded before the crowd. The Argentine, who has not had a pre-season to speak of, will have to wait a while yet for his debut.
It also remains to be seen if Neymar will feature this weekend following his late return to pre-season training after playing for Brazil in the Copa America, but Mbappe will play against Strasbourg amid ongoing talk of a move to Real Madrid.
