Barcelona president Sandro Rosell says he's no friend of Real Madrid counterpart Florentino Perez.

Rosell, though, insists he doesn't have anything against Perez.

"I'm no friend of Florentino. Friends? I have four or five in life, no more," he declared.

"I don't see pressure from being president of Barcelona, but an exciting challenge. The only pressure I have is when I'm called by my daughter's teacher and I'm convened for a meeting."
