Cesc admits his departure may've upset a section of the Gunners support.
He told the BBC World Service: "I will always have Arsenal in my heart. They gave me everything as a person that a footballer can ask for. I know some people felt bad when I left and they didn't understand my reasons - they considered I left in bad manners.
"I owe him nearly everything and I owe him my reasons.
"Arsenal fans have been nothing but amazing to me and that's why I don't want to keep talking too much because they have moved on, they are doing well.
"I am very happy for them and let's see what the future brings."
