It's nothing to do with Murray being here or Baldock scoring more. Hemed's goals last season (17 of them) dried up when LuaLua, and then March, got injured. Baldock was also injured which affects both Murray (as seen at Preston and Huddersfield) and Hemed.
He started scoring again when Knockaert arrived as he was getting some service.
What, you mean it's a team game ?
