Neymar will find all the support he needs at Paris Saint-Germain after the Brazil superstar questioned his long-term future in football, head coach Mauricio Pochettino has promised.

In May, Neymar signed a new contract to stay with PSG until 2025, and this season he has been joined by Lionel Messi at the Parc des Princes.

Along with Kylian Mbappe, they could forge one of the great strike forces in the game, although at this stage the trio are still finding their way as a combination.

Despite the challenge of making such an exciting alliance work, Neymar has said he is unsure whether he has the "strength of mind to deal with football" much longer and would likely play his final World Cup in Qatar next year.

"Neymar is an honest person and a player who expresses his feelings quickly," PSG boss Pochettino told a news conference on Thursday.

"But I think his mental strength, considering he has been playing football since a very young age and has always had the media spotlight on him, I don't think there are any problems.

"Sometimes things are taken out of context, but I have no doubt he enjoys his football and I'm sure he will play for many years. I don't have any doubts about that."

Asked about mental health in football, in relation to Neymar's comments, Pochettino said: "This is something that exists in high-level sport. As the coaching staff it is our job to have certain tools in place to help our players.

"But I also don't like talking about this in such a surface-level way, because I think it is much more complicated than that. Certain things cannot be taken out of context and we can't simplify these situations, particularly ones that we are not going through ourselves.

"We are always very worried about our players' physical and mental well-being, so we are always available to help them."

Focusing on Neymar, Pochettino said: "His passion for football is on display with us every day so I have no doubts about that."

The former Barcelona forward has experienced a slow start to the campaign in terms of his productivity, scoring only once and having just two shots on target in his first seven club games of the season across all competitions.

Yet only Pele (77) has scored more goals for Brazil than Neymar (69), who has won the Confederations Cup (2013) with his country, along with an Olympic Games gold medal in 2016.

His suggestion that the 2022 World Cup may be his last also reflects that Neymar will be 34 by the time the 2026 tournament comes around.

It remains to be seen how PSG are as a force by then, but for now they are expected to win every game, which made the 2-0 loss to Rennes before the international break such a surprise.

That shock reverse followed on from a victory by the same scoreline against Manchester City in the Champions League, and Pochettino reflected on the Rennes game again on Thursday, choosing to describe it as "a slip-up".

On Friday, his team tackle Angers at the Parc des Princes, when they will be expected to get back on track, albeit hampered by absences caused by stars such as Neymar being on World Cup qualifying duty this week in South America.

PSG are unbeaten in their past 21 Ligue 1 games against Angers (W14 D7), which is their longest run without defeat against a single top-flight opponent.

After his Nations League efforts for France, PSG will hope to have a firing Mbappe on the pitch. The striker has failed to score in his previous four Ligue 1 games, his longest top-flight drought since March-May 2018 (six games). None of his past 17 shots in Ligue 1 has found the net.
