The home crowd pleaded with Graham to stay during his second-half cameo appearance, and defender Ashley Williams has revealed his team-mates are doing the same.
"We've just been saying to him that we want him to stay, saying 'don't go'," said the Wales captain.
"We all want him to stay, he is a top player and has done well here. We definitely don't want to see him leave, and I think if you asked any player here they would say the same thing. We want him here.
"He is going to make the decision on whether he stays or goes. He has to make the right decision for himself and his family and his situation.
"Obviously, we are telling him we want him to stay, but it is his decision whether he stays or goes and we will back him whatever he chooses."
