Barcelona president Sandro Rosell stands by the price paid to land Santos star Neymar.

Neymar signed for Barca in a €57 million deal earlier this month.

"We don't have any problems explaining the 57 million euros it cost [to sign the player], but we have some confidentiality clauses that we cannot break. If other parties want to explain, we have no problem if they do so.

"Neymar's signing was a sporting priority and he's a footballer that excites Barcelonistas, as we saw when he was presented," said Rosell.
