The superstar forwards were supposed to help the Ligue 1 giants savour Champions League glory, but they have failed to deliver on that remit

Lionel Messi and Neymar arrived at Paris Saint-Germain amid much fanfare in the summers of 2021 and 2017 respectively, with their additions to star-studded ranks at Parc des Princes expected to help Ligue 1 giants claim an elusive Champions League crown.

Two iconic South Americans have failed to deliver on that remit, though, with a prestigious European prize falling out of reach again for an ambitious outfit from the French capital in 2021-22.

A disgruntled fan base have taken to airing their frustration at a lack of progress on the field, with those struggling to justify lucrative transfer fees and contracts becoming targets for those on the terraces.

PSG fans made it clear to two men expected to shoulder a considerable burden of expectation that they are not immune to criticism during a domestic outing against Bordeaux on March 13.

Messi and Neymar saw their names jeered when the starting line-ups were announced in Paris.

The whistles continued once the game had begun and a couple of supposedly match-altering talents found themselves in possession of the ball.

Both were targeted as a result of PSG’s latest early exit from the Champions League, which came at the last-16 stage against La Liga giants Real Madrid.

Mauricio Pochettino’s side led that contest by two goals on aggregate at one stage, but saw Karim Bemzema hit a quick-fire hat-trick at Santiago Bernabeu to send them packing.

Neither Messi nor Neymar was able to make a telling contribution on Spanish soil – against former rivals from their days at Barcelona – and are considered to be offering little return on investments of faith and funds made in them.

Neymar has taken in regular spells on the treatment table during an injury-hit stint in France, while Messi registered just seven goals through his opening 26 games for PSG – alongside a healthy haul of 10 assists.

While Messi and Neymar have incurred the wrath of those in the stands, Kylian Mbappe remains a hero to many.

He did his best to find a way past Real Madrid on a continental stage, as he registered goals home and away, but was let down by those around him.

The World Cup-winning France international is yet to sign a new contract at Parc des Princes, meaning that he could drop into the free agent pool this summer – with the Blancos one of his suitors – but PSG fans appear prepared to forgive him for causing another unwelcome distraction as they continue to back his cause.
