Buckley said he was uncomfortable with the fact that in contrast to the powerful image of the players'stand on racism was the fact that there was a former player who insisted he suffered racism when at the club.
"Clearly the thing that needs to be spoken about is the fact that with Héritier we have a disgruntled player,ex-player,in this particular issue of racism,"Buckley said after the match.
"I speak for the club generally but I have to speak for myself (on this). I am not comfortable with the fact Harry,sorry Héritier,feels like he has been belittled and diminished in our environment.
"I have not spoken to H since 2014 and I would love to speak to him again. I would love to have him come to his old football club and see what we have become and the culture of acceptance,a celebration of difference,no matter your colour,religion,whatever your upbringing has been.
"We have grown as an organisation,we were growing when he was there and he was a big part of it and we are still growing,but I am really proud of the club we are now."
