Why Neymar's star risks being eclipsed by French sensation

Neymar heads into the new Ligue 1 season at something of a crossroads, with the Brazil superstar seeking to make up for an underwhelming World Cup campaign.

After becoming the world's most expensive footballer when he completed a €222million move from Barcelona to Paris Saint-Germain, many expected Neymar to force his way into contention for the 2018 Ballon d'Or, an award that has been duopolised by Cristiano Ronaldo and Lionel Messi.

Ronaldo and Messi have won five Ballons d'Or apiece over the last decade but, going into a World Cup year, Neymar was widely tipped as the man to potentially break their run.

But this year has not gone to plan for Neymar.

PSG were knocked out of the Champions League by Real Madrid with the forward having little impact, fracturing his foot before the second leg and missing the last two months of the domestic campaign as Unai Emery's side completed a clean sweep.

Neymar returned to fitness in time to lead Brazil into the World Cup, but only scored two goals as the Selecao were beaten by Belgium at the quarter-final stage.

Brazil's below-par performance in Russia contributed to Neymar being left off the shortlist for Fifa 's Best awards - a year ago he was third behind Messi and winner Ronaldo.

Not only did Neymar fail to sparkle on the big stage, having missed Brazil's semi-final humiliation at the hands of Germany on home soil four years ago due to injury, he was roundly criticised for what was widely perceived to be play-acting and over-emotional behaviour throughout the World Cup.

Striking a conciliatory tone in an advertisement for sponsor Gillette, however, Neymar appeared to indicate he is ready to turn over a new leaf.

"Boot-stud on the shins. Kick in the spine. Stomp on the foot." said Neymar. "You may think I overreact, and sometimes I do. But the truth is I suffer on the pitch. You have no idea what I go through outside of it."

Both players have been the subject of strong transfer speculation during the close-season, especially since Real Madrid's shock sale of Cristiano Ronaldo to Juventus in a deal worth €112m.

Madrid moved to deny their interest in Mbappe and Neymar despite the duo being the most obvious transfer targets for the LaLiga giants, who were led to a third consecutive Champions League crown by Zinedine Zidane in May.

Neymar has long been linked with Madrid, dating back to before he left Barcelona, although a switch from Camp Nou to the Santiago Bernabeu would have been politically impossible for both clubs.

For that reason there were then suggestions Neymar's move to PSG was intended as a stopgap switch that would then allow him to join Madrid and take his place as Ronaldo's heir.

Neymar, for his part, has insisted he is staying at PSG - at least for now - but the rumours will not go away.

Mbappe, however, has emerged as the more exciting prospect. The teenager is nine years younger than Neymar and universally liked around the world for his mature, humble attitude and thrilling style of play:

Mbappe clearly loves playing football, whereas Neymar often appears burdened by the massive expectations thrust upon him.

Having moved from Barcelona partly to escape the shadow of Messi, Neymar is now at risk of seeing his star eclipsed by Mbappe, who has all the pieces of the puzzle to develop into the best player on the planet.
