The Selecao star has settled in Russia and is looking forward to regaining his top form after recovering from an injury
The Brazilian moved to Luciano Spalletti's side in the summer of 2012 but was linked with a move to the Premier League over the course of the summer, but the former Porto man is happy in the country.
"I feel free here," he was quoted as saying by Fifa.com.
"We can walk in the local parks with my wife and children without any kind of pressure from journalists or football fans."
"There are Brazilian restaurants here but we all also enjoy Russian cuisine very much. The only thing which has caused me some discomfort was the cold weather in winter.
"But the city looks very beautiful in winter when everything is covered with snow."
The winger has recently recovered from a thigh injury and admitted that he was not playing at his full potential in the recent games against Atletico Madrid and Rostov.
"Of course, I wasn't 100 per cent ready for the matches with Atletico Madrid and Rostov and failed to show everything I can do in these encounters.
"But I feel myself getting better and better with every new day and I hope I will be able to play at my top form pretty soon.
"I hope that the entire city will celebrate our success turning Nevsky Prospect into a white and blue river. I believe that will come true some day."
