Argentine legend Carlos Bianchi regards Barcelona star Lionel Messi as the game's greatest.

Bianchi is convinced Messi stands alone.

"I see him as the best player of all time," he told La Garganta Poderosa.

"People to say to me: 'He's not a world champion', but Messi plays a game every three days and he is great every time. If he does not score, we miss it.

"We have to be aware that before us is a player the likes of which we will never see again, for his performances and his consistency."
