Neymar has been one of the world's best young footballers for several seasons, but he has doubts if he'll ever reach the level of a Lionel Messi or Cristiano Ronaldo.

"I don’t know if I’ll ever reach the level of Cristiano or Messi," he told Globoesporte.

"They are better than any other player on the planet today. I don’t know if I’ll reach their level but I aim to improve every day. I always want to better myself.

"Everything takes time. I’m growing each day. Coming to Europe has been a great experience. I was happy in Santos, but I wanted a fresh challenge and I hope to keep being happy."
