“I’ve changed a lot since my arrival in Italy,” he told Globoesporte.
“Here the defenders are constantly alert and use any means to stop you moving. So I had to work hard to adapt.
“And I changed the way I play because I was training in Brazil exclusively on the legs, I only concentrated on the ball.
“Here, however, I realised that you must use cunning, use your arms, push and pull shirts.”
Lazio are up in third place in the Serie A standings currently, and the South American playmaker feels that two victories over Roma and a win against AC Milan have made the difference this term.
“These are important games, which give leverage to a player’s career. The great thing is that things have worked well in these games and the team have grown stronger as a result.
“Last year I remember that in some of these games we played well but could not be decisive. This year, things have been different for me and the team. It’s been a very good period.
“We could be even higher in the standings, but there have been unexpected things - in January we sold a few players and many others were injured - all this has hurt the team and is regretful," he admitted.
Lazio face an away trip to Catania on Sunday, a game that kicks off at 15.00CET.
