Current Spain boss Robert Moreno worked as a coach under Luis Enrique at the Catalan giants, a time during which he got to see the Argentine in training every week.
Asked about what it was like to deal with Messi on a day-to-day basis, Moreno claimed that, because of the 32-year-old's brilliance, he is not somebody that is actually coachable.
"He's the best player in history. It was incredible to see him in training every day," Moreno told BBC Radio 5 Live.
"What you can see in matches on TV, we would see every day. Leo plays another game to everybody else. You can't train him, you are with him – he is football.
"You help the other players to adapt to him, his movements and decisions.
"With Leo, it's like The Matrix. He can see the movement of the legs of the opponent, and he sees the movement of the goalkeeper and has the ability to react.
"There's no other player in history that has done that. Leo is god."
Messi played 158 matches under Enrique's management, scoring 153 goals and assisting a further 68 strikes.
