Messi has long been likened to his fellow countryman, with the two players similar in terms of style and stature.
However, Simeone has said that it is wrong to compare the duo.
"You can't compare [Messi] with Diego. I don't think it's fair to compare players from different eras. There's Pele, Di Stefano, Maradona. You can like one or the other, but it's a personal choice," Simeone told Ole.
