"Many people tell me I am the heir to Maicon, as I am similar in terms of strength and pace," he told the Gazzetta dello Sport.
"We don't know each other really, as we are from different generations. We never played together at Cruzeiro, but I did train alongside him in a few games between ranks when I was in the youth team.
