Anderson says being injury free has made a big difference.
“It took a long time for me to settle in Italy and my football maturity has just arrived recently, but I am still young and have a lot of time ahead of me," he told UOL Esporte.
“I have no regrets in football, because even the bad moments helped me to grow. It wasn't all wine and roses, but the scars of the past are there to remind us what we've learned and to do differently.
“I am very grateful to the Lazio fans for showing me such affection. I am happy and proud of what I have done. I think this has been my best season, above all since December.
“Last term I was limited by the pain, but now I am 100 per cent fit and that is fundamental for an athlete at this level."
