Happy we've a 2 week break now, ample time for Pardew and his staff to have a word with Ba. Might be able to look at some things in training, whatever it takes to up his spirits ad get him back in the goals.
His game has definitely suffered a little bit but I think he's a decent enough - and spiritual - person to not get too disheartened as long as the team is doing well. Naturally he won't be too happy at the moment, hence his frustration today. I don't think he's the type to misbehave though, I don't expect to read or heat about him getting in fights with the manager or anything.
For half a season he was the star of the show, everyone loved him, the media were crazy about him... now his quiet mate from Senegal has 'stolen' all the limelight from him. Going a few games without scoring must be difficult to take for any striker, no matter who you are or what contribution you're making to the side in the meantime.
