Murphy strikes me as a confidence player. When he came back from his loan, where he clearly did well, he looked confident and scored a couple of goals. He was making intelligent runs, which for the most part were not seen by the man on the ball and looked a handful.
But then he went a few games without a goal and the confidence just ebbed away. He stopped making those runs and the ball started bouncing off him and, at times, he didn't look 100 % committed.
I think it's true he wants to be down south, but I also think he's certain in himself that he can cut it in league 2 but he's not sure he has what it takes in league 1.
Personally I think most players who shine in league 2 are good enough for league 1 because there isn't a huge difference in standard, but I'm not sure he believes that.
