Aguero credits Man City form to having Giannina with him
While Carlos Tevez has used his family's inability to settle in Manchester as an excuse for his own unhappiness and cover for pushing for yet another multi-million pound move, Giannina and her husband have shown them how it can be done.
Talking in Naples, at the run-down stadium where his father-in-law Diego Maradona worked his miracles, Aguero told The Sun: "Maybe Manchester is not an easy city to adjust to for players from South America. But I'm doing well so far and the main reason is down to my wife.
"She understands City are an important club and one that made a decisive bet on me for their project.
"Giannina and I have been together now for four years.
"She is the woman in my life and my support system.
"She grew up in the football bubble and knows all about it. That is an enormous help. Ever since we became engaged, she told me 'Look, I know football, I understand how it works. I will follow you wherever the game takes you'.
"And that is exactly what has happened.
"She followed me to Atletico Madrid from Buenos Aires and, in many ways, that was more difficult than going to Manchester. When I signed for City, she was here with me within four days.
"That was so important to me. That proved just how much she DID understand.
"Now we have our house here and we are enjoying every minute of it. It is so important for a footballer to have a happy home life - especially when you are playing in a foreign country."
