Ligue 1 team, owned by Qatar Sports Investments, dumped out of European Cup at last-16 stage yet again
PSG project questioned after deadline to win Champions League title 'in next five years' expires
After defeat to Barcelona on away goals in the Uefa Champions League quarter-finals in 2013, Paris Saint-Germain's Qatari president Nasser Al Khelaifi stated the club's objective was to win the competition "in the next five years".
That deadline expired with Tuesday's limp defeat to holders Real Madrid in the last 16, leaving the French side as far away from being European champions as at any point since Qatar Sports Investments (QSI) bought the club in 2011.
For all their lavish spending, PSG have still not made it past the quarter-finals of the competition this decade, and there have now been consecutive exits in the last 16, the 5-2 aggregate loss to Cristiano Ronaldo's Madrid coming after a spectacular collapse saw them crash out in Barcelona a year ago.
The strategy after that defeat was to commit to paying the two biggest transfer fees in football history last August to sign Neymar and Kylian Mbappe for a combined €402 million (nearly Dh2 billion), an attempt to buy immediate success on the biggest stage.
It has not worked, with Neymar left watching Tuesday's 2-1 defeat at the Parc des Princes that sealed PSG's fate from Brazil, where he is recovering from a foot operation.
"All that for that", was the headline on the front of sports daily L'Equipe on Wednesday, a reference mainly to the bold transfer strategy.
"We believe in our players. We want to continue the project, with the two of them because they are the future of the club," Al Khelaifi said on Tuesday when asked if the club's investment should be called into question.
Seven years after QSI's arrival, PSG have still managed to beat just three teams in the Champions League knockout stage: Valencia, Bayer Leverkusen and Chelsea.
That is a damning statistic for a club with their means and ambitions.
"We will continue, as much as patience allows, to build a team which can win in the future," manager Unai Emery said on Tuesday. "When I came here I said I was sure this team can win the Champions League. But it's a process."
Soon to be out of contract, Emery will not be given another crack at the competition in Paris. The club will look for a new manager, and they will be tempted to go for a big name after the failure of the Emery experiment - the Spaniard won three Europa Leagues with Sevilla but has never won a Champions League knockout tie in six seasons of trying.
They also need to revamp their squad again, and replace the likes of Thiago Silva, Thiago Motta, Dani Alves and Angel di Maria, all in their 30s.
The club insist they are not worried about falling foul of Uefa's Financial Fair Play rules, even if a premature European exit will mean a shortfall of millions of euros.
"We are relaxed about it. It is more of an issue outside the club than inside. It is March and we have until the end of June. There are no worries," sporting director Antero Henrique told L'Equipe last weekend.
But in the meantime another period of soul-searching will begin for PSG and their owners.
"Now is not the time to talk about change, everyone is upset. We want to calm down before working out what needs to be changed. We have time to think about that," Al Khelaifi said on Tuesday.
PSG still have three domestic trophies to go and win before the end of the season, but that seems instantly less appealing once the big prize of the Champions League is no longer up for grabs.
