Jo has hit out at the way he has been treated by Manchester City - and admitted he does not want to return.
The Brazilian striker joined City for £18million last summer but made only six Premier League starts before he was loaned to Everton.
The 22-year-old scored two goals on his debut for the Toffees - trebling his league tally in the process - and has revealed Goodison Park now feels like "home".
Jo told The Guardian: "The people here have given me much more support. I felt it from the first moment I came to the club and every footballer needs that kind of care.
"(Everton captain) Phil Neville is never too far away, always asking if I am okay, if I need anything. But it's all the players, not just Phil. They have all looked out for me. It feels like Everton is my home now."
Regarding his time at City, Jo said: "I think it's a little unfair. I was only there six months and I would call that an adaptation period.
"In my opinion, you should have at least one season to adapt before everyone judges you. Unfortunately no-one really thinks like that.
"I find it strange because I had quite a good start and then for some reason - something that has never been explained to me - I was suddenly no longer playing.
"I was training well, like I normally do, but I didn't have happiness."
Now Jo, who revealed he has not spoken to City manager Mark Hughes since his move Everton, is hoping to stay at Goodison Park rather than return to Eastlands at the end of the season.
"If I had to choose, I will choose to stay at Everton," he said. "But if I have to go back to City, I will go back. I believe in myself and, if I go back, I will try to show what I can do."
