Barcelona star Lionel Messi is looking forward to testing himself against Marcelo Bielsa's Athletic Bilbao.

Bilbao are coached by Bielsa, the former Argentina and Chile trainer.

Lionel Messi said of his fellow Argentinian: "I was not coached by him, but he is a person I admire for what he did with Argentina, Chile and Athletic.

"He is a technician who would have appreciated me."
