"Neymar is a very smart guy, he knows that Messi is ahead of him.
"Neymar is joyful, he is a tremendous guy. He and Messi are two great players with different characteristics.

The Blaugrana supporters could be given their first taste of the Neymar-Messi partnership for the club's Spanish Super Cup clash against Atletico Madrid in August.
