He told Mundo Deportivo: "Why did I choose Everton despite the many proposals? Thank God, I had several proposals. It's a problem, but a good problem.
"It's a team that fights with the big guys and I think we can do a great job there."
Mina also left the door open to an eventual return to Barca.
"If I left with the idea of returning to Barca? Yes of course. Barça is wonderful and I would like to be there forever. Colleagues, coaches, assistants ... I thank them all. Now I have to focus on Everton, which is now my club and I will fight to death for them because they showed me their confidence. If the opportunity arises, I want to get rid of this thorn."
