Despite the challenges of the move from the British islands, Lewis is finding enjoyment in his new surroundings.
Ahead of facing Belarus with Northern Ireland on Saturday, he joked: “I guess I’m going to have to give man-of-the-match performances every week now.
“There is such a rich culture of football out there, it’s amazing. I hope it will go on into the long-term future.
“And I am very proud to be a Northern Irishman playing in Brazil.
“The hotter climate makes for a different intensity in the football and, at times, I feel far away.
“But there is a rich culture of football and some hugely-talented players who have played in the Premier League before.
“It’s a massive challenge for me — and one that I am embracing with both hands.”
