Because everyone has mate. How can you seriously say that when you turned your back on the manager years ago?
Honestly Wenger has done nothing but harm Bellerin, he has run him in to the ground and supplied him with no cover. On top of that he has had to hold the right wing all by himself offensively and defensively with his shocking tactics. The club then denied him a move to Barcelona which he didn't complain about and just got on with it, only then to get constant abuse from the fan-base. In all honesty I can't blame Hector for wanting to leave, he is being let down here and won't fulfil his massive potential at this club in it's current state.
