It’s almost impossible to predict the future trajectory of Neymar’s career.

The Brazilian has already achieved so much since earning his first professional contract at Santos in 2009.

With 60 goals in 96 appearances, Neymar is the third-highest goalscorer for his nation behind none other than Pele and Ronaldo.

At club level, the 26-year-old boasts a trophy cabinet most players would be content with even if he retired tomorrow.

Neymar won two La Liga titles and the Champions League in four years at Barcelona, before his £200 million transfer to Paris Saint-Germain made him the most expensive footballer of all-time.

Since then, the forward’s efforts to step out of Lionel Messi’s shadow have yielded modest progress.

Excluding the Champions League, PSG completed a clean sweep of honours during Neymar’s first campaign in the French capital.

However, only the biggest prize in European football, along with the most prestigious individual accolades, will propel him to heights of Messi and Cristiano Ronaldo.

While such success will inevitably take time, there’s already talk of Neymar potentially returning to Spain - either back to the Nou Camp or for a fresh challenge at Real Madrid.

Messi - who’s still very much the main man at Barca - was asked for his take on the prospect of a reunion with his former understudy, to which he didn’t completely shut the door on.

“It would be difficult," the Argentine told Marca.

“We would love it if he came back for what he means as a player and in the dressing room.

“We are friends, we enjoyed nice moments, as well some which were not so nice, but we spent a lot of time together.

“It is undoubtedly difficult to imagine him leaving Paris. PSG won't let Neymar go.”

There’s definitely some truth in Messi’s final point about the Ligue 1 champions’ likely reluctance to sell the player spearheading their huge ambition.

However, reports of PSG’s continuing failure to comply with UEFA’s Financial Fair Play regulations indicate they could be forced to cash in on their biggest assets.

The most obvious solution would be to sell Neymar or Kylian Mbappe in an effort to avoid a more severe repeat of the €60 million fine they received in 2014.

But even if PSG cut their losses on at least one member of their €400 million duo, will it be enough to escape the attentions of UEFA?
