Barcelona star Neymar admits he's unhappy with his current form.

Neymar believes he's yet to hit top gear.

"I think that I can do much more, I did okay last season, but now I want more," he told Sport.

On Lionel Messi, Neymar adds: "It is easy to play with the world's best player. It is always easy to play with the best, easier than with those that are 'more or less'. To play with him is an honour. When I saw him from afar, when I was in Brazil, he was like an idol for me. I thought that he was the best. Now that I am close enough to him I see that yes, that's what he is."
