Some fans on FB are using this post to defend him as "not a Judas" or whatever they said.
Problem is: these posts are standard nowadays. All players post them whether they enjoyed their time at the club or not. Some are probably told to post it and given the photo to do it with.
Or they get someone to do it for them.
The precise reason this has been posted is because of the backlash and to try and change opinion as you've stated above.
