Barcelona captain Lionel Messi expects a competitive El Clasico next week against Real Madrid.

Messi believes that Zinedine Zidane's men will be in good shape at the Camp Nou.

The Argentine emphasised the idiosyncrasy of a derby game such as the Clasico, where anything can happen.

"I expect a very strong Madrid," Messi said.

"They are very decent in these games.

"They are special matches, no matter how one or the other comes into it.

"We are both in good form, but they are moments [where the form book goes out the window]."
