#1 Kylian Mbappe's threat
Paris Saint-Germain invested heavily to make Neymar the most expensive footballer in history last summer, paying a whopping £200 million to acquire him from Barcelona and linking him up with elite attacker Edison Cavani at the Parc Des Princes as well as signing a prodigious Kylian Mbappe to help the Brazilian quickly establish himself as the best player on the planet.
However, things are taking a twist right now - Mbappe who was signed to help Neymar become the best footballer in the world is actually overshadowing the Brazilian at the moment, having led his nation to claim the FIFA World Cup recently, being heavily tipped to win the Ballon d'Or award ahead of his compatriot as well sitting on top of the goalscoring charts in the French division.
There is no doubt Mbappe is the biggest threat to Neymar's dominance right now and at just 19, the French prodigy still has age on his side and he could provide stiff rivalry with his compatriot for a long time. Therefore, Neymar could be convinced to leave the Parc Des Princes and return to Barcelona where he will automatically be the heir to Lionel Messi who turns 32 in 6 months time.
