He told BBC Sport: "For me, I left on good terms.
"I don't want to comment on what Arsene (Wenger) said - he had to say something to the fans and I don't want to say any more.
"I've been back to London to visit them - in February I went to the training ground to see everyone and even with Arsene I still have a very good relationship.
"When you work hard and have great results it creates something emotional. I was at Arsenal for four years, I learned so much and I discovered the very highest level of football with them.
"I can't say (if I would go back to England) because I'm here and I'm enjoying every day of my life. I'm having so much fun playing for this team so it's difficult to say. We'll see, you never know."
