Barcelona chief Andoni Zubizarreta insists there's no problems with Neymar's fitness.

Medical tests have shown Neymar is carrying a low blood count.

"We would have liked him to have been in perfect condition, but not many players arrive perfect for the preseason. We'll help make sure he's in the right condition, it's not a concern," said Zubi.

"In these cases, players are used to training a different way to us and they have to adapt to how we work. That's what we do in the preseason. There are quite a few days left before the league starts, although it is unlikely that he'll be 100% adapted by then. But we can clearly see that he's quickly getting a grasp of our type of football."
