Jo admits he'd like to stay with Everton rather than return to parent club Manchester City when his loan expires.
He told the Guardian: "If I had to choose, I will choose to stay at Everton. 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.
"If a new manager comes in, you don't know ... I just have to show what I can do, whoever is the manager. Whoever it is, I am confident I can show I am a good player."
