Barcelona legend Johan Cruyff has warned his team of the threat of Arsenal ace Robin van Persie.
Cruyff admits he's a big fan of his fellow Dutchman.
"Van Persie is a good finisher, an even better left player and is strong in the air," said Cruyff.
"He scores goals galore and is extremely fresh, because of his injuries earlier this season."
