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."
