He told Sky Sports: "I feel great, I feel very, very good. Arsenal for me is my home, I love to be here every day. I think that it is normal when you go from a rival in London to another club, and they pay big money for you, some people will doubt me. But I just knew my qualities, I believed in myself and obviously the manager and my team-mates helped me a lot, because it's not always easy in those situations.
"Everyone was there for me, everyone was ready to help, and I think that's why at one point it just started working. I think I grew up a lot, it just happens when things are not going your way, you grow up as a person and as a player as well."
