The 28-year-old joined Manuel Pellegrini's side in the summer, leaving behind a Shakhtar Donetsk dressing room with a strong South American contingent featuring 10 fellow Brazilians.
But with no compatriots amongst the City squad, and yet to learn the English language, Fernandinho has had difficulty adjusting to his new surroundings and team-mates.

"It is a little complicated because I don’t speak English so when my team-mates are talking in English I don’t understand what they are talking about.
"When I was at Shakhtar, I had Brazilian team-mates and I used to spend time with them, but here I'm alone. I see and talk with Rafael and Anderson but not all the time. So yes, I miss Ukraine sometimes."
Fernandinho, though, is keen to overcome his homesickness as he looks to impress enough in the Premier League to earn a call-up to Luiz Felipe Scolari's Brazil side.
"I came to England because I thought it would help me to get back in the Brazilian national team," Fernandinho continued.
"I’m not thinking about moving back to Brazil as I want to end my career in Europe, and I think about playing 10 more years!"
