I'm not sure about this whole Ba throwing a strop about playing left of a 4-3-3.
Don't get me wrong, it is possible/likely and maybe during the summer he said that if he wasn't given chances in the middle he would re-evaluate his position. But surely Pardew, after such a s*** run, could have put his arm round him and said "Dembs, look how s*** we are. Could we just have a few games trying the 4-3-3 from the end of last season? It's not your fault, it's the other players and injuries and I would really appreciate it. Wouldn't you rather be winning games?"
Players must have a desire to win or else they wouldn't make it so I fail to believe that Ba wouldn't agree to that. If he did refuse then get rid. More worryingly is that Pards isn't asking.
